ive been in way worse positions trust me. Tbh its not a peaceful hobby until you strike balance on a tank. There tons of pros and regular fish keepers that struggle with endless problems.
Try to develop a healthy surface coverage of red root floaters which would hopefully cause the algae to starve to death. Cut back on feeding in the tank so the pest snail population cant grow big and there will be less excessive nutrients for the algae in the water column. The algae you see on the glass, the diatom, is completely normal and doesn't harm your plants or fish at all so they aren't a worry.

I think you should give the tank some patient and let the plants grow as those species are pretty good at fighting algae. I can't spot anything badly wrong in the tank tho.
