well i am bipolar and to tell you the truth go w/ your heart. your heart no one else's.
i have fibromyalgia and bi polar. i have actually tried to push my husband down the steps, i have this uncontrolable anger and hate. so be glad your girl is quiet. i flip out right away. i pushed a friend of mine, male over 200 pounds about 6'1" tall into a water cooler and i sprained his ankle and those are just a few examples. your girlfriend is probally on anti depressents and they will attack your sexual drive. i was sexually abused 2 but i don't feel that is the case of not wanting to have sex. most people that are truely bipolar have sexual tendenses (spelling) and a hard sexual drive. they also will shop until they are in major debt like me.
those are true basic and classic symptoms of bipolar disorder. she will gain weight because of the meds. be careful my shrink had me on 10 pills and i overdosed without knowing because i was in a land of my own from the meds. keep an eye on her.
i hope this helps whenever u think u have it bad be glad your not my husband, we have been together since i am 15 a total of 20 years and he still puts up with me. up to u and u only.
