Cant sem to control my temper?

I can't seem to control my temper. I get very angry over very little things and will question if life is worth living and yes I do have depression but I also have no friends just a wife who doesn't really show much affection or love for me and it doesn't help that my dad is also depressed and my mom doesn't help much. I try to make friends but it seems no one has the time or care to make new friends. Also it oisses me off when I see more happier people around me and I wish that I could be happy for once.
