A psychiatrist shouldn't really scare you. Basically, its a doctor who specializes in helping defeat their issues. If it is their opinion that a medication might help you along the process more effectively, you should consider it. I have had problems with depression and such for nearly three years now, and have been taking anti-depressants for the same amount of time. My psychiatrist told me to consider this:
If someone has been depressed for one or two different times, 4-6 months of medication may be all they need.
If someone has been depressed 3 seperate times, they may need a year or more of medication.
But, if someone has experienced depression 4 times or more, it is likely they will need medication for nearly the rest of their lives.

These 'rules' are not true in every aspect, and certainly situations chnage for people. Hang in there. Just live day to day!
