#sewing problems

I wanted to sew my own clothes since I was a little girl but the confrontation with the dream has been going nightmarish. Everything is extremely pricey, so far I paid 300pln (supporting small shops yay) for a top that I can find for 100pln, i can't cut anything properly it all looks choppy af but I don't have space for cutting mats etc, the sewing machine sometimes just skips looping the thread on arbitrary basis and when I look for any explanation people are acting like it's some sort of esoteric ritual brushing it off with "EvErY maChInE Is DiFFeReNt" or listing every single element as "could be wrong". If even there's anything wrong with my machine I can't afford another one. I'm really thinking it's a hobby for people rich enough for having a whole dedicated sewing room not for someone in a one room apartment who is losing her mind over running out of space. Maybe I'm too stupid to figure out how to fix machine problems but I'm not gonna get smarter at this point. No, courses are available only in big cities. The only reasons I find for keeping going are sunken cost and theoretical clothes that maybe would look wearable that didn't manifest in any attempt and surely would look disappointing compared to pattern pictures. It makes me sad to think about wasted time and money, and to give up on an ambition but sometimes you gotta tell your inner child to shut up. Should I just give up and sell everything?
