I’ve lost everything. What do I do?

Wife hates me, has expressed divorce for a year. Can’t afford therapy because I’m paying for hers; she does them with her mother because she didn’t want to do them with me. The only genuine joy I find is with my son, and she’ll take him when/if she leaves. My family doesn’t talk to me anymore because of differences of lifestyles. No, I don’t have hobbies or friends, I don’t even know who or what I like anymore. Slaving at two dead end jobs, was put on PIP at one. Depressed and anxious and angry all of the time. Lacking faith, the most I do is pray and I feel nothing but shame then. If it wasn’t for my belief, I would’ve done “it” but I’m scared of the afterlife.
