Is there any hobby outside the house you could start doing, that could maybe even lead to you being around people more? Like maybe you could do rock climbing, or kickboxing, or swimming, or a sport, or some sort of class (cooking/art/design/coding/music/improv/literally anything), or a meet up / club relating to your interests. Just, something! Something youre interested in and can go to and be around others who are also doing that thing. At the bare minimum, at least you're going out and doing something you enjoy. And at best you can meet people you like who are also doing the thing you enjoy, and see them once a week or month or however often you're able to engage in this activity.

If there's no social activity you can possibly go to, then it is still worth exploring a hobby you can cultivate. Even just something you can do on your own that is fulfilling and fun for you, and maybe even engaging online in communities focused around this hobby.

When you're 18 will you be able to go to your dads house? Honestly at 17 you're already old enough to decide where you want to live, especially considering you've already got a GED and a job. I don't know what these issues are that she will cause for you if you move, but honestly man if it's what you really want I do think you should find a way to make it happen and just be prepared for whatever these issues are that she's gonna cause you, plan ahead to minimize what she can do.
