Having trouble keeping up

It’s been 6 mon since my breakup of 5 years, & I thought I was doing really good but I think I might’ve been suppressing it… idk… I’m irritable, I’ve been crying the last 2 days, having trouble keeping up with the house & cooking for I’ve been getting my daughter food out 3x a day ☹️ haven’t don’t laundry or dishes just feeling so drained tired & sad… I know this might be a reach to some but one of my close friends has recently ended her long term relationship as well so we’ve been hanging out a lot but every time I hang out with her I notice I feel like this after.. again idk if this has anything to do with her or I’m just suppressing emotions bc I had a really good mindset about me and my ex not getting back together and I was better off without him… now I don’t know what it even is that I’m upset about.. could I be taking up her emotions😟😟 I was doing so good, I was getting dressed everyday, cooking now it’s a drag to even get up in the morning and do anything I literally just leave and get the baby breakfast.. need advice & some advice on some ideas to pick up my spirits
