Hi, you're right, stay away from negative
people! The problem is, when you are
bi-polar and have active symptoms, you
don't know it.
Therefore, sometimes when people are
telling you you are weird or are negative,
sometimes, they are right. Just keep
this in the back of your mind, after a
while, you can start to recognise symptoms
in yourself that are a tip-off to a
depressive or manic episode.
And no, it's not your job to educate
people about your condition. But if you
care about someone, you should share what
is going on with you. They probably,
actually, care.
Best of luck
