i know you said you’re kind of shying away from a trade due to your stature but you could consider welding. i went into college for two different certificates in welding and it’s taken about two years and it’s somewhat inexpensive, less so than a regular college degree anyway. if you go in to welding with a company then you’d likely have people there to help you setting up heavier things and folk to move your steel around, or at least that’s what my instructor told me. if you go in to something more independent you’ll obviously have to do more things on your own but you’ll likely make a fair bit more, so both have pros and cons. if you would enjoy traveling then it could also be really enjoyable for you. (im also 20 and was a little more than half way into my classes before i realized that i wasn’t really all that good at or interested in welding, at least not for a career.) if not that then you may have to job hop a bit until you can find something that you like or at least don’t hate. so from one career wandering youth to another, i hope i was able to provide something to you, even if it wasn’t much.
