What do I even do now?

I just turned 18 and because of my shitty childhood and troubled high school years, I don’t have anything to show for it. I lost my job so I’m unemployed, no car, no high school diploma. I don’t even know what I should aim for first, I mean of course I need to focus on getting a job but then what? I need an apartment of my own as well, my living situation is extremely unstable. My ride places currently is my boyfriend, but I hate having to depend on him and work around his schedule and want to do things for myself. I’m just lost because I don’t have parents to look to since they are both severe addicts. I’m so overwhelmed ive barely done anything and I feel bad because my boyfriend has been trying his best to provide but no job will call me back and for both ride convenience and sleep schedule I’m looking for a night job, which makes it harder. It also makes it difficult because I don’t want to do food service or heavily customer service oriented jobs. And do I even need to focus on my ged? Ive quite honestly just lied on applications about having completed high school.
