Feeling utterly stuck in life and want to salvage my life and still enjoy it but don't know how
I'm 26, Male. I haven't gotten to college and still live at home with my mother. I keep trying to right now focus on writing and drawing, but I just can't seem to improve at art, and I'm very weary of writing and nervous i'm not probably realistically not going to make enough money with it to live. I sort of feel stuck from a few problems. To paraphrase to explain my situation but avoid venting, I have one of those helicopter mothers who thinks if you leave the house you'll get shot and killed, and my father ripped me out of high school against my will and sued me at 18 and took my college fund which is another story for another time.
After the court stuff settled, I still live with my mother, but she doesn't really lift a finger to help me but does thankfully financially keep me afloat in the house and doesn't charge me rent. The downside is that she doesn't like me bothering her but also is afraid if I leave the house I'll somehow die, so she actively works to prevent me from leaving the house to visit people in other states, and I probably can't do much until I have enough money to just move out all at once, and my original plan was to hopefully make a career from my room making art and writing online somehow, but that's not working, I ironically find it harder to improve at art now than I did when I was young and some thing with writing. My mother's only advice for a job really is Target, which I don't know what a financial path like that would look like, assuming they even hired me, but I assume the wage wouldn't be enough to move out anytime soon unless I'm wrong, and once I move out, I still don't have a degree. I'm stuck because I guess like most people, I don't want to work a job I don't feel like fulfills me and waste what little of my 20s I have left here, but I don't know what to go to school for if its not for art or writing, but I don't know if those are going to pay my bills. I don't know what I'm doing anymore and I feel scared about reality crashing down on me more than I feel lost or anything else. I don't have the passion anymore for writing and drawing and Game Design, but I'm assuming I'm just under the weather from the situation and am hoping the passion might come back once I get out of the house. I'm not a homebody, I love exploring and traveling and was happiest the one time I got to go to a city with some friends back when my father still lived with me and hadn't lost his mind yet, nothing makes me happier than being in a car and seeing new things, but I just... feel like my situation is beyond my ability to solve from here. Is there any outside wisdom that could help?
I have light interest in History and Engineering (been over a decade since I last did it though) my best skill in school was math, if those help any. My original goal and "dream" life was to write books, make art, marry an artistic woman of some kind, and go to conventions together and then when we come back home, make games with a team of people we know/hire somehow and/or work with said hypothetical wife to help with her goals as well, but the older I get, the more I... feel less confident about making it there.
