Stuck in dead end jobs and need a change and career advice not sure where to go from here

Hi everyone im new to reddit so please bare with me, also typing on my phone so if formatting is odd thats why lol.

Im stuck and have been for over 10 years. I live in a dead end city with very few opportunities and far less things to do, think no enrichment in my enclosure lol. Ive worked retail and a few other jobs here and there but the pay has been barely enough to get by. Ive tried schooling, first our of high school I was going for graphic design. I was always artsy and I loved to draw i wanted to design characters for video games, however....I was not supported in this field by my parents. During my first semester my grandfather who I was close to got very sick and due to a lack of communication with my professors and even more depression than normal. I failed in this semester and being young and sheltered i was told no more school i needed a job. I worked mostly retail after. I tried going to school but school isnt my strong suit despite trying my hardest. I went for medical but I just couldn't grasp the subject and fell behind. I worked other jobs but nothing seemed to last long. I currently work at a gas station and its so far the most stable for me but it some days only barely sustains my needs. With the cost of living so high and the inflation its hard to make ends meet. Sorry this is a bit of a ramble lol. I guess ive just struggled with many options that never seem to stick. Im stuck and I dont know where to go or what to do. I love being creative and im a big nerd. I dont know what a career i can do that doesn't involve much schooling but i need something where I can be expressive and creative but no where around me has these options. Any advice? Sorry if this was a bit all over the place I guess I just wanted to get my feelings out there and see if any of you all have experienced the same. Thank you so much for your time.
