Being unmarried, I volunteered to care for my father, he passed at 90, but during the 2 1/2 years I did that I never had any help from my siblings, if I asked for some assistance ' the answer I got was you volunteered. At the same time my 33 yo back in in 2006 showed up at my door(he'd been on his own since he was 18, went into the military for 4 years in 1991, then got a job and was on his own until Apr 2006. He moved in but after a few days I knew he was not leaving, after numerous attempts at getting him help, I finally had to have him admitted for psychiatric help. Started on meds, counseling, he has a diagnosis of bipolar schizoaffective . I am in deep depression and can't find a moments peace or tranquility...I at a loss, if I stay here, I don't know what will happen to me, if I leave I don't know where to go, and what will happen to him...and i feel very guilty.. What do i do?
