I haven't officially seen a doctor, but I've basically diagnosed myself with Generalized Anxiety Disorder.

I'm constantly having negative thoughts; I'm terrified of losing someone close to me, and I'm always thinking something is wrong with me. I get one little pain and I automatically think I have cancer or something. To use an example: my mom has had an earache for a couple weeks and it's just now starting to get worse. The obvious answer is that she has an ear infection, and antibiotics should do the trick. But the way my mind works, I've convinced myself she has some sort of tumor on her brain and that I'm going to lose her. This thought tonight made me burst into tears and I haven't been able to stop crying since. It's gotten to the point now where my worry and tension are starting to interfere with my normal life. I don't want to see a psyciatrist or get on meds. Is there anything I can do besides these doctors and meds to make my constant worry go away?

First, you need to talk to someone. It doesn't have to be a psychiatrist (who by the way is a medical doctor that specializes in mental disease) but can be a psychologist (who is specialy trained to help you work through problems or issues and they dont prescribe drugs (although some are starting to)). Psychologists dont think of you as a patient, you are a client. And there is a big difference. Second, you need to want the help, otherwise you wont go and your issues will get worse. Also, if you are employed, most employers will pay for you to see a psychologist, up to several sessions! So money shouldn't be a deterrent (check with your HR benefits). You shouldn't self diagnose yourself either, you may have something very easy to work through that will make everything better once you go though a few sessions; but if you are in the slightest a hypochondriac, you can make yourself physically ill with worry. So, relax, take a few deep breathes, and check to see if there is a counsellor in your area. I am sure they can help you most adequately.

I get that way too. Its mind control. Try and pull yourself to reality. I can do it at times, control it. Going for a walk, fresh air, open space...it helps me.

Its hard.. its our cross.

Could be some anxiety, but it also sounds like there's some other stuff at work there.
You should see a physician soon, and be sure to be totally honest with him or her.
Good luck.

Honestly, I would say no. Sure, there are some people that believe that you shouldn't take meds for things like that, but if it is interfering in your life, then you need to seek help. The fact that you recognize that you have a problem is huge and will help you in your dealing with the problem. You don't have to be on meds long term, sometimes people need the meds to calm them initially, and once they realize and rationalize that the sky isn't falling, they are able to wean themselves off the meds and lead a normal life. You will always have stress and anxiety, everyone does, but you shouldn't let it run your life. Take Charge!!

Unless you are willing to see the falsehood of your thoughts and also see that they are maladaptive and challenge them, you won't need to see anyone. However, this is interfering with your life and that is not good so I suggest seeing a cognitive behavioral psychologist. You don't need to be on meds if you can change your negative thoughts and challenge them successfully

Okay, of course my #1 answer would be that you absolutely need to talk things out with someone. A professional therapist would be the best. Next, find a church adult to talk to,or a school couselor. Someone needs to help you see that life if actually good and you shouldn't dread everything that could go wrong, (which probably never will go wrong.) Your mom doesn't have a tumor!!! Start thinking of something good!!! Take it one step at a time. In the morning when you wake up, say to yourself, "This is going to be a good day. Then take baby steps ... you know ... little things... I'm gonna fix my hair nice today! ... Another thing you could start is writing in a journal, just three things every day that you're thankful for.

You're not trying hard enough. Couldn't it also be a combination of psychotic depression, histrionic personality disorder, and atypical early-onset paranoid schizophrenia?
Brought on as a side effect of neurocysticercosis, ie, pork tapeworm infestation of your brain tissue.

Either that, or you're one of the test subjects being targeted by the Department of Energy with the ELF towers or the microwave vans. (Or even the HAARP array and behavior-modification cloud seeding, if your whole neighborhood seems to be acting funny.)
Don't Google any of that stuff, BTW- you know they've logging every search term you ever entered, right?- if they decide you know too much, they might decide to give you cancer and get you out of the way.

...If all that doesn't do it for you, well, maybe you just need to look back on all the times in the past that your fears have proved wrong, compose some -realistic- betting odds, and finally you need to come to terms with the absolute fact that both your mother and yourself WILL die eventually- and probably in that order.
All of us are going to lose our mothers, and all of us are going to die of something.
Time spent worrying is time not spent enjoying your finite, uncertain life to the fullest.

this state of anxiety comes when one feels secluded keep urself busy and also occupied and accompanied so that u wont get such thoughts kids or pets r good companions for such persons u get occupied with their stupid thought provoking questions and activitiesu wont get time to think about other things try to be extrovert talk to people and good friends so that u will over come within few months may be 3 months dont even try to remember u experience such thing u will be fine its not a big deal
