My energy goes through bursts, advice?

My day depends on my mood and I hate it so much. Like I want to check out a lot on my to do list but I don't have the energy and just spend days hating myself. I do a lot of baby steps but never go forward after ticking one task off. I also feel lonely, feel like a loser for not going out alot and trying my best with my swimming hobby because i wanna be alone. I neglect my family, haven't been taking care of my dogs the way i want to (my mother helps), i dont hangout with people apart from coworkers. I also have health issues i neglect like sleep habits and teeth. This looks like a weird rant but I would appreciate some input. Thanksl
