Why do i feel sad for no reason?

Sometimes I'll be feeling fine and out of no where I just start feeling sad even though I have no reason to be sad. When I try to figure out why I'm sad I can't come up with an answer.

I don't think it's depression because I've been depressed before and it was much worse than what I'm going through now.

THE IS ALWAYS I REASON WHY WE GET SAD I THINK FOR YOU IS SOMETHING DEEP IN YOU, TRY TO LOOK IN YOU WHEN YOU FEEL SAD AND LEA-SIN TO YOUR INNER VOICE NO ONE CAN HELP YOU BUT YOU THE SADNESS IS ALL ABOUT YOU,SOME PEOPLE LIKE TO BE SAD BECAUSE THEY DO-NT LIKE TO FEEL GOOD ABOUT THEMSELVES RE-SEN BEING THEY WE NEVER GI-VIN A CHEANSE OF HAPPINESS WALL THEY WE YOUNG BUT I THINK YOU NOT YOUNG NO MORE SO IS TIME YOU FOCAS ON LOVING YOUR SELF AND ALSO LET THE SADNESS HAPPINE BECAUSE THAT IS THE WAY WE COMMUNICATE WITH OUR SELFS GOOD LUCK ON YOUR WAY OF LOVING YOUR SELF

DEPRESSION.... seek help or talk to someone

Its depression, it doesn't mean your crazy, there are mild cases of it. i go in and out like that all the time. it sucks but there is hope. they make very low doses of medicine that help so much.

You may have some kind of depression, you might seek medical advice

You probably are suffering from some kind of depression. There are many types. Please seek the advice of a professional.

Chemicals in your brain my be causing slight depression; nutrition, sunlight or exercise may clear that imbalance right up. My depression (much more severe that yours) has been cured by using an all natural mineral supplement that gives my body what it needs to function. Sometimes all our bodies need to fight a problem is a simple mineral or vitamin and it takes care of the healing part. I've seen some amazing recoveries with all natural solutions. Don't take a drug for help as they will only treat the symptoms and not the underlying problem. email me any time for nutrition or health questions.

a reason ur not really thinking of but ur brain is somehow and its like depression but moreso due to hormones or w/e u wanna call it. i wouldnt worry about it much as it will pass but just try talking yourself out of it and make yourself happy again. "think happy thoughts"

spunds like depression, maybe not as severe as it ws before, but it might b acting up agn..

have u been checked for bipolar? it sounds that u may be mildly bipolar. im bipolar and i can usually recongnise it in others. look up bipolar and check what u r experencing against what symptoms bipolar has. i hope u feel better. another thing r u pregnant? when u become preg. u may experience unexplained sadness...

There are different levels of depression so even if it doesn't feel like it, it could be a mild form. Or you could have Dysthymic Disorder. Not everyone has enough serotonin in their brain to make them happy or optimistic all the time. You probably just have decreased levels. There doesn't have to be a reason for you to feel that way, it just is because that's how your brain's chemicals want to function. I'm the same way but I am now on meds and I have to say that (unlike what 'natural healer" said) they DO REMEDY the underlying problem that's how they get rid of the symptoms because they work on the molecular level (hence the name "medication") in order to increase the serotonin or dopamine. So if you are in this state for a long period of time, to the point that it affects your life, then you do need to see a doctor and consider meds. People like "natural healer" that don't really understand what long term depression is should not be giving advice to people. It is impossible to cure true Dysthymic disorder or mild persistent depression with healthy food ect. Hers was probably temporary depression if that worked for her. I've had a lot of psychology because I'm in the medical field.
First off, don't just jump to any conclusions, give yourself more time before thinking about meds. Your INITIAL steps can be exercise to increase serotonin and talking about it but don't push your limits, if you need professional help because it last a really long time (no matter how mild it may seem) get help.
