I know how you feel, and it sucks. The only advice I can give you is to find something new to knock you out of your funk without knocking you up(don't ask).I'd recommend a vacation, though that's not always feasible. I know someone who went on a vision quest, and if that kind of thing works for you then go for it. As for my family, we'll pull through and my father will be fine. It's all about keeping your head up and pressing on.
Yeah my parents split and now my father is in my hospital. Truth be told, I've never had everything I've ever wanted. don't get me wrong, I'm spoiled rotten and as far as things go I've never really had to want for anything. But everything else in my life has always been fucked up. Like my parents. When my mom left my dad tried to kill himself and now he's in the hospital. He'll be just fine but he'll have to stay in there for a few months. Just to name one of a few things that are really fucked up in my life right now. Based on the little I know of your situation I'd say you just need something new. A breath of fresh air.
