One of my eyes has an extremely weak muscle as to where I was going to go legally blind at age 10 if not for the two surgeries I had them. I still need glasses and if one eye is covered even with glasses, my vision goes to 20/1000 and I become violently ill.
My nose was broken when I was little so I have a deviated septum. This means I suffer chronic sinusitis (stuff nose) and my whole life I sound like I am sick. I can't sleep for more than a few hours in a row without waking up due to not being able to breath. So my entire life I have been sleep deprived despite allotting for 10 possible hours for sleep every night. So imagine how you feel with little sleep.... my exhaustion, irritability, and chronic depression all stem from not having one good night's sleep. I'm finally looking into getting surgery for it, because I'm teaching outside of the US so going to the doctor doesn't cost a fortune.
I also suffer horrible migraines whenever the air pressure shifts ie it goes from sunny to rainy quickly (again due to the nose)These migraines are so bad that I have a hard time seeing and they will not go away for over a day. Extra strength antihistamine migraine pills help. Normal headache medicine didn't. When all the stores were closed for a special Korean holiday, I spent the weekend curled up in a ball crying on the floor due to a headache that lasted 38 hours.
Add in the fact that I didn't talk till I was 6 (was being taught sign language which I wish I kept up) and I'm transgender (tried to end my life at age 7 by drowning, and again throughout my childhood even coming close with hanging) and my life is quite the challenge. Though both of those problems are fixed (I'm an English teacher who just got her book picked up by a literary agent and I transitioned to female some years ago and pass perfectly). In a year I will get my nose fixed and everything will be perfect =).
