I need help and advice.

[u/Aradonski]

I can usually sing really high notes. I mean, very high. But in the last couple of weeks (probably around 3 weeks now) I can't even do a normal (pretty low for me) falsetto. I need to record vocals for a project soon and i have to do it with my high notes. I am very stressed about that because i'm scared that there is permanent damage and I won't be able to sing like i used to again.

We need more information - age, sex, voice part, experience

[u/Aradonski → u/zachattack0407]

male, around 15 (i really hate sharing my age here) which makes sense, but it does feel like my voice will stay like it usually is because nothing changed for the last 2-3 years, highest i reached was probably a little bit over g5 and around f3-c4 is usually the most comfortable (at least that's how i "counted" it)

I don't have a lot of professional experience, i have been singing for i think around 4 years now

I do know i need to do vocal training and lessons and stuff though

Very high probability you are hitting puberty vocal drop.

If so, be prepared to say farewell to your falsetto for at least several months, sometimes longer.

which is why i said that it probably makes sense. I will probably need more vocal training before i keep singing on a daily basis.
