I legit have nothing to be happy about

I (15M) don't have a functional family, I'm so broke the only device I have at home is the cellphone I'm typing this with plus I struggle to get interests and hobbys because of it, I've never been in a relationship: I had this thing going on with a girl time ago and we sorta had a crush on each other, but as we graduated we took different paths and we haven't spoke to each other anymore. I wish I could move on but my mother recently works at her mom's and she often talks about her. Plus recently I've been bullied by some girls in my class. School is really hard and I'm not even sure if I'll pass. I do have some friends, but most of them live far from me
