is it emotional abuse or just over reacting?

I've never thought that my family abused me in anyway but lately my friends have started being concerned that my mom is and has been causing damage for years now, and I just don't know. I personally don't see it but this is also what I'm use to, so I don't even know if I would see it you know? Anyway, it would be really nice to have some more feedback from other people, thank you.

I always thought that my mom had treated me good, but looking back I'm not too sure anymore. When I was a kid I was a picky and kinda messy eater as a kid and my mom didn't understand that there were some foods i just couldnt stomach, but when i threw them up she and my step dad made me re eat it. And if i threw that up, i had to eat it again, and if i made a mess, they made me eat on the floor like a dog. As a kid I was always trying to impress my mom and step dad so they would be happy with me. I would clean house, I joined teams, choirs, color guard, band, musical theatre, ballroom and so many other things but they never seemed to care. They never seemed happy. I was earning the money and paying for this stuff my own but they would always complain about concerts or performances even though I told them that they didn't have to go. And when they did go, it was just silence on the drive back home. It really hurt to be honest, because I had worked for months on something and I was so excited for them to see it and they didn't seem like they cared. They would tease me about everything, and I ended up super insecure and anxious. I got into a lot of toxic and abusive relationships because I just wanted to make somebody happy, but I didn't know you could make someone happy who was just using you. I would cling onto any sign of kindness because I wanted to badly to make a friend my parents wouldn't hate. I still get excited by people being nice to me but I've given up on making friends because they all leave. About a year or two ago, my mom and step dad got in a divorce, and everything changed. My step dad and step siblings are super nice to me now and want me to come over whenever, and my mom started to go out and do things with me. We moved into one of her coworkers house and it was fun for awhile, and then it changed again. I didn't feel like she really cared about me anymore. She'd go on trips for days or just leave over night somewhere and she was constantly going places. I made my own dinner every night, or at least I tried, but it's difficult to cook for one you know? I spent so much time alone. I didn't have a lot of friends, and the ones I did have lived really far away and were almost always busy. I ended up meeting my currant boyfriend at a ballroom comp and we really hit it off. His friends liked me, I liked his friends, everyone was super sweet and my mom just let me go hang out with them whenever, but then she decided out of the blue that my bf was a mess and irresponsible and I didn't even know why he had his life together, But for whatever reason, she hated him. She still let me see him but she hated him. Then she started talking about sex. She said she would be okay if I had it and to just let her know so I could get on birth control. So I asked if I could go on the pill just in case, and she said okay, but never I'm pregnant, and I'm actually happy about it. I know I'm young but I'm excited to have a kid with someone I love. But my mom and our roommate keep making fun of me and saying rude comments even though I've asked them to stop. I don't even go upstairs very often anymore because almost every time I do I end up crying or deeply hurt.

I'm sorry for the long post but I just had a lot to say I guess. Thank you for reading and please give me some ideas I really don't know what to do. I had to quit my job because my mom made me and so I don't think I can get emancipated, and my step mom's been pretty brutal in the past too  (she asked me to walk behind her because I was to ugly to be a part of the family) so I don't know what to do I don't know if I even have any options
