Struggling to Move On After a Breakup

I just ended my 3 year relationship because I was not reaching my goals and instead focusing on caring for my boyfriend. I love him so much but he was not trying to make things work and I felt discouraged and overwhelmed. Now I am living alone but can't get myself to feel light in my chest enough to get things done. I left my daughter with my mom so I could be a better mother but now I don't even have a job or know where to start. I want to buy a house asap but I have no job and no drive to really do what I need to do for my baby (7 y.o). I was suicidal before I left in March 2020 I see her every weekend but I want to be able to take care of her and her needs but it seems impossible when I can't do it for myself.
