Struggling

Hi everyone. I (25f) have been having a rough 2 months for 3 reasons. First, my boyfriend (31m) and I haven't been having the best relationship lately. He's stressed with his PhD program and going through a depression I think, which has caused him to distance himself from me. I've tried to connect with him like we did before, but he's pretty much been unwilling to do so. The past few days I've just been finally accepting the situation for what it is. I can only do so much for it. Second, I live at home with my parents. Lately they've been making me feel like a huge burden. It's been so tough to not have support at home. Third, I'm working as a substitute teacher and I hate it. I've been doing it for a year and I'm so disappointed in myself. Just about everyone I know seems to be doing much better than I am. I know comparison is the thief of joy and I'm trying to make steps to just be happy with myself. I'm stepping away from social media, I'm reading books again for my own pleasure, and I'm trying my best to not worry about the future. Any words of encouragement? I'd really really appreciate any words at all. Thank you everyone <3
