FESS Surgery - do I get it?

I have chronic maxillary sinusitis and have done for 2 years. Originally was told by my GP it was chronic rhinosinusitis but I had a CT scan and my ENT said I had CMS and a slightly deviated septum to the right.
I saw my GP first in march this year and was given mometasone spray and naspetin cream (nasal passages were so dry and kept cracking and bleeding). I was also using saline rinses too.
I didn’t really notice that much of a difference so I gave up using it all which in hindsight sight wasn’t the best idea probably.
When I saw my ENT he recommended FESS to open the passageways and clear everything out, because I said the meds didn’t do anything.
I’ve got 2 months to come to a decision on whether I want the surgery or not but in that time I’ve got to use the spray and rinse. I suppose 2 months is a good trial run with the meds again to see if maybe there will be an improvement.
I suffer with anxiety, especially health related and ive been complaining about my sinuses for months, nose is always blocked, pain and pressure etc but as soon as surgery was mentioned I panicked and my brain started trying to convince myself that my CMS isn’t that bad and maybe I’ll be fine. I’m really struggling to make a decision, I’ve been trying to do a lot of research into it and tbh reading the risks etc is freaking me the hell out.
I’ve had other surgeries before and not really been concerned but there’s something about this one that stresses me out, especially as it’s something right on my face. Even now I’m in pain with my nose and know that it won’t get better without FESS.
Can anyone give me their opinion or experience of this that could help me decide? Everything I’ve read online is kind of the same info just different website and I can’t figure out what side I land on.
If anyone has had FESS please tell me your experiences and whether it’s worth it. I’m sure I can’t be the only one to try and convince themselves ‘oh it’s not that bad’ even though I’ve been complaining for 2 years…..
I’m just a little scared about the surgery and I’m panicking the worst will happen
Thanks guys!
