How can you get over phobias?

I have a bad phobia of needles. Ive broken bones which hurt a lot more than needles, but for some reason i freak out when i need a shot, etc.

seek psychological counseling. Hypnotherapy is helpful for some people.

That's a very common fear for people to have. I freak out with needles too...and I'm a nurse! (Trust me, giving shots or IV's are WAY easier than getting!)
Treatment for phobias is usually desensitization, meaning they expose you to your phobia until it doesn't really bother you anymore...or you can function in society. You don't have a phobia that really interrupts your daily living. (Some people are scared of germs, pennies, or whatever...and it really effects them daily)
Treatment may be different for you. I'd go talk to someone. I HATE shots and I just got a Hepatitis B vaccination and honestly I was SHOCKED it didn't really hurt! I know I'll be less of a baby in a month when I get another one. :P

I have severe anxiety, I get nervous about doing pretty much everything from going to the store to talking to people on the phone.

I have been working on it for the past few years.

the best way to help you with the fear is to confront it.

what about the needles makes you scared?
Then ask yourself what is the worst thing that could happen?

I had an issue with needles when I was younger, but when I was diagnosed with a thyroid problem I had to get my blood drawn on a monthly basis. so I have been dealing with needles for a while.

the more you confront what scares you the less that it will scare you.

I watch them do everything which helps you know what to expect and lessons the fear.
