I've Had Clogged Ears For A Very, Very Long Time,

I've had clogged ears for a very, very long time, since I was 5 years old and am now in my early twenties. The clogged ears may have been due to me, when I was younger, carelessly running into an area where there were many bees and getting stung in the ears. Anyways, my ears are always clogged and I can't think clearly, yet I can remember things well, oddly enough. Sometimes, I see dots in my vision too, which is probably related to the ear issue. I also sometimes feel liquid or something (maybe from my ears?) flowing down my throat and it feels weird (or it could be indigestion that's causing my clogged ears?). Also, probably related to the ear issue, I always feel out of it and can't focus on college stuff, sometimes strangely dream while I'm awake, like I'm at two places at once. My nose is also stuffy a lot and corresponds to how clogged my ears are. When I was younger, I always had problems with my nose being extremely clogged and went to the hospital to deal with it. I also strangely feel unreal a lot of the time and sometimes my ears become very clogged and I start becoming sad and at the point of crying (not by choice but rather for some reason because of the fluid buildup). Is it Eustachian Tube Disorder or something else? What should I do? I went to my ENT doctor and they were basically of no help.
