I know you are struggling. I was there too my friend. It's not easy to live like this, it does take time and sometime LOTS of it. I would suggest that you seek some therapy (not talking about meds/drugs). Talk it out with someone gain some vocal support and feedback. I can handle TONS of pain, because I have seen more pain and obstacles in my life than anything else. I got tinnitus as a teen and i had the classic/low level hum/static noise. I use to go crazy and I was so scared. This was when my tinnitus was not even noticeable, unless i was in complete silence (room/atmosphere with no noise). Now I have tinnitus that is 10 times worst and I show no emotions or hardships towards it(95% of the time).
I remember as a high school student (someone that use to have a 2.4 gpa btw) we were introduced to a program called "where there is a will...there is an A". They use to force us to watch it. I never did and my grades were horrible and I almost never graduated. I was in junior college and got motivated to change my life and I went from a 2.4 gpa in my past to a 3.3gpa and I was accepted into school of psychology(EVERYONE said i'd be a failure. EVERYONE always doubted me.) I was so proud to prove people wrong (done this MANY times in my life and I LOVE IT!)
I did all of that and my father didn't pay (he promised he would if I got better grades) for my college and it broke my heart. BTW, I have had poor hearing since i was in my teens as well. In school I could never fully take notes because my tinnitus and hearing were horrible. I could not understand what the teachers would say, so i'd pay people to take notes for me
(I was a clever cookie)
My point is this, IF there is a WILL in YOU (which IM SURE IT IS), then you will make it and adjust and live a good life. It's not an overnight thing, it takes GUTS, GLORY, EFFORT, TEARS and most important of them all PATIENCE to get it going. You CAN do this, I know you can.
Give it some time buddy, you will be ok
