Hes been a friend for over 15 yrs.Hes pretty much a part of my family. Hes kinda done this before , drifts in, drifts out , always comes back around, he has depression spills where he isolates at times. Me and him have a pretty close relationship and he sorta did this again where he drifted off . I'm struggling a little without him , know without the real story , hard to help. I think he knows he can always come back , we just have a special bond and I'm really the only one who knows what ls going on with him , was wondering if maybe cause he confided stuff to me , his own fam doesn't know maybe hes embarrassed now .his other friends don't realize somethings going on with him , they just think oh this is him , he dies this leaving and coming back thing , but I know its more cause hes told me. would love to hear stories from others who struggle with dissassociation /emotional issues /commitment fears/ maybe bipolar also .
