I have talked about this very subject in great lengths with my health care providers. There is a VERY strong correlation with my quitting drugs and my developing bi-polar. My psychiatrist says that someone may have a predisposition to bi-polar naturally, and drug use especially stimulants (cocaine)can bring it on like gasoline to a fire. I can say this while i was on drugs i did not feel i had bi-polar at all in fact i thought i was fine, i thought i was a normal teenager experimenting with drugs so i think that's normal maybe how she might be feeling too. During the first few years after my drug use i didnt want anything to do with my family either, my mom still called and i hated it...and you know what..now that i'm diagnosed..and on medication and doing well...i really appreciate her calls. I just want to say to you....even if she doesn't seem to want or appreciate you...some day she will..
