Ksgirl02,
you are not alone. Yes, you can experience feelings that people are judging you, and that you won't be good enough. It is a persacusion complex, which goes hand in hand with paranoia, that are classic bi-polar symptoms. You need to educate yourself on the signs and symptoms if you are going to understand yourself. When you become familiar with the warning signs, you can head yourself off at the pace before you go into a major episode.
Go to the library or search the web for more information. The more you know the better you can know how to handle your life in the future. You are still young and have a lot to look forward to, since my diagnoses I have met and married my husband, bought a house, made and kept friends and am having a full and wonderful life. Not to say that occasionally there aren't any bumps in the road, but life's road is long and winding.
Good luck,
mia
