Fear of being ignored

I really didn't want this to be my first post here - I first wanted to finish the piece I am currently working on, but it seems like I won't sleep until I spill it out.

TL;DR: I put a ton of effort, I don't want it to be a complete waste.

I started music education when I was 6 and composed my first, extremely simple guitar piece when I was 9. Some time afterwards I would switch to a shrunken symphonic-like orchestra and stay there basically until today. Since early 2020 (age 12) I've composing on a quite regular basis, and the oldest pieces I am happy about to this day come from early 2023 - around the release of MuseScore 4. During all that time, the orchestra gradually grew until it became near-full symphonic orchestra.

Now I'm 17 and on top of the last year of high-school I do both the second-to-last AND the last year of afternoon music school all at once, all to finish everything in time before college.

I managed to have 3 live performances already, which might be impressive given my age and the ensemble I'm writing for. People around me, both musicians and non-musicians, both my friends and people I've never met, compliment me very often, in fact so often that I struggle to get any criticism or areas for improvement, which is also quite annoying in it's own sense. But it all still doesn't matter if the industry requires extreme amount of luck to get in.

And I said all of this to show how much effort I have for my musical progress, especially last year, which has been not only physical, but sometimes also psychical struggle. And I really don't want it all to just become wasted.

And I don't need much - I just want to have even a small group of people who will stay interested in my works, and I just want to be able to hear my music live from time to time.

And usually you end such posts with a question, but I don't really know what question to ask. I know that the odds are low (or are they?), but I also know I have my whole life in front of me and it might be still too early to give any verdict. For now, I can just ask - am I pessimistic or realistic?

And thanks in advance to all the people who read this whole rant, I'm sure you know stuff better than me. I'll also probably post some of my works soon in a desperate attempt to get some criticism.
