I’m so mentally exhausted why can’t anyone diagnose me

I’m only 24 :(.
I’ve been “sick” since 2020. Yet I’ve been to countless drs in this span of time. So many different Medicines, Testing, imaging and it all is clear there’s nothing there. Come back and see us in 3 months they say. It all started with a dry cough and night sweats. Now I’ve developed so many other symptoms like Severe Fatigue to the point I’m falling asleep for hours during the day and I have really dark under eyes, I still get chest pain and cough if I inhale too deeply, my night sweats have gotten even more drenching, chronic pain/numbing/pins and needles on my entire right side, I can’t even walk right without moving my right leg weird, I’m having so many falls every single day, I’m covered in bruises constantly from it, my right hip constantly pinches, my right hand randomly drops stuff I can’t write well without it hurting, my elbow gets stuck in place, sometimes I get these moments of numbing on my right cheek/mouth. The last few months I’ve become extremely emotional or quick to aggressive. I feel like I can’t control myself. My vision in my right eyes blurry sometimes even with contacts/glasses. I get moments of confusion and can’t remember what I was going to say or I say the wrong words. I get fevers off and on. I get sick bad when I catch something it takes me 1-2 weeks or more to get better. I get chronic severe migraines that medicine never touches. I feel like I can’t catch my breath even the slightest movement leaves me breathless. I loose my vision, hearing sometimes and I feel like I’ll pass out. I’m 24 and I can’t even run anymore. Not to mention the chronic stuffed up nose I’ve developed since February. Not to mention the countless GI issues I have yet no diagnosis there too. I just want to be able to enjoy life and play with my son outside.
