Can I ask you guys for some life/career advice like unironically

I've made two posts in this subreddit before and gotten a lot of replies but I always wind up being overwhelmed by the response and end up not replying to anyone, but I want to ask something more general:

Can you make even a half way decent living doing this if you aren't that smart? I made a lot of shitty life decisions and wound up graduating with a Computer Science degree at the ripe old age of 29 in 2025 and I had horrible grades, sub 3.0 GPA, shitty state school, no internships, no real interest in it honestly. I've been stuck in shitty retail/food service jobs my entire adult life and don't really know what to do anymore. People always make fun of me when they find out what my degree is in but it's like well I can't really do much with it, at least on my own personal level.

From my previous posts on this subreddit people have been urging me to go into help desk so I can get out of retail but the truth is I don't really even feel qualified for help desk. I don't know anything about anything and I don't know how well turning in a resume that only has my degree on it and a bunch of McJobs on it is going to go over.

I honestly don't know what to do and only have been looking into going into IT because there seems to be a more clearly defined and accessible entry point than SWE (not so much that it is less competitive) but I'm also sort of dumb. This is the only other field my degree is applicable to and it feels like trying to make this work is the most efficient path especially since I live in poverty and can't afford any other degrees or extensive job training. I'm also 30 and can't really rely on my parents much longer at all.

I don't know sorry my situation seems pretty hopeless I'm just grasping for anything by asking internet strangers cuz I have no one in real life to ask
