Feeling off

My baby is 7 months old and I love him, I hate to see him hurt, upset, or cry. I’m very proud of him and my Dream has always been to be a mom. I feel horrible though because I can never get him to sleep. I feel like nothing is ever enough, he gets fussy so easy and I always try new ways to soothe or entertain him. Most of the time I feel like being a mom is a chore rather than enjoying it. I usually don’t want to be around him (but I miss him when I’m not around him). I’ve been thinking about leaving a lot, blocking everyone my family, my boyfriend, and his family and never talking to them again. I’m really quick to anger but most of the time, I don’t feel anything at all. I just don’t really care about anything. I quit my job ( we are financially secure but I never thought I’d quit). No matter how much I sleep I’m constantly drained and tired. I don’t think this is ppd or a phase I just think I made a mistake when I thought I should be a mom. I truly do not think anything medication or therapy wise will help. I’m not sure what to do to feel different?
