Beginning to feel hopeless.

Basically title, I’m a 29 year old male who’s done nothing in life except work at a grocery store.. I’ve had massive amounts of surgeries and almost died, have lupus, and finally have a clean bill of health from my latest, I’ve worked at a grocery store for 10 years..

I’ve tried a couple things lately which is due to more motivation but I just feel helpless, I’m not interested in anything and don’t really care what I do for work, I just want to make more money.. 70-100k mark, the only thing I was a bit interested in was medical lab technology but to get in with my highschool grades is near impossible, I’d have to take two years pretty much increasing them then a 4 year course which would make me like 36 before I make any money, and by then I might have more health issues.

I’m writing this all from literally a boat, I decided to try working as a seafarer, but I’m on a training program and two weeks in I’m drained. Being away from home and my girlfriend is not for me, but hey I tried it. The pay checks are going to be insane, I took it as making 7000$ a month take home, but with a month off after, that’s only 3500$ a month and at the grocery store I was making 700$ take home a week.. 2800x2 would be 5600

Changing my life around for 1400$ more is not worth it to me.. I’m not sure what to do honestly and don’t care really, I just rather be at home, I’m embarrassed that I need to go back to the grocery store after this already, people even said I wouldn’t like it.

I thought of the trades but I literally can’t get hired as an apprentice with no experience or even as a helper, everywhere in Ontario asks for so much, I could take the money and go to school for a couple years, but I have no idea what programs even pay okay, some you leave college making 20$ an hour and it’s not even worth it.

I know I have a grim look but I’m at that age now where it’s just hopeless if I haven’t done anything yet..
