You write well, and you got B’s and C’s in school. This tells me that you’re smarter than you think, but abuse and/or lack of proper support has had an effect on your development and self esteem (which isn’t surprising). You are still at a very young age, when a lot of people are still trying to find their way. I’m not saying any of this to minimize your struggles, but to give you at least a bit of perspective. A lot can change in a year or two when you’re only 23!
For specific advice on resources available to you, it would help people to know at least which country you are in.
