Kinda feel like giving up

Recently I’ve been getting headaches and vision issues and I’ve seen doctors but nobody has been able to diagnose me or they just keep giving me diagnoses that just don’t add up. I’ve got so many scans done and all came back clear. It’s frustrating as I’ve been trying to live with these symptoms (headaches, pressure behind eyes, light sensitivity) for weeks now and honestly it’s becoming a little too much for me to handle mentally.

Like sometimes I feel like just ending it, I don’t wanna die but I honestly don’t know how much longer I can handle not being able to see cause it’s having an effect on my life, especially my work. I just don’t know what to do anymore, kinda just want to give up if I’m being honest
