I want success. It took me so long to figure it out

From about 8, maybe younger, I was severely neglected and occasionally physically abused. When i turned 14 I moved with my dad. During freshman year I skipped class, smoked weed, ran away, cut, wrote a suicide note, had horrible grades, etc... Sophmore year wasn't much better neither was Junior. It got better with each year though. It's my senior year and I got Straight As for the first time, I'm looking for a part time job, and doing what I'm supposed to. I have medical issues which makes things hard. It's hard to stand up for even 10 minutes or sit for more than 60. Along with other things. But now I'm thinking about the future as I watch an episode of hoarders. I realize that I want to go to college to be a sonographer. (Ultrasounds) I want to have a nice house with nice dishes that's organized. I eventually want a family. A future with no stress over bills. Comfortable on a nice neighborhood. A place where all the kids friends can come and ply in a special room dedicated to games. Xbox, pool, air hockey, Etc. I want it. I strive for it. I'm going to start studying for sonography now, before college.
