Confused

Okay so Sunday i was boxing with my friends and my best friend knocked me out and i fell but i caught myself and i had a black out. Then later on that day the whole day Sunday i was painting the bathroom with the windows shut and the bathroom door shut on accident and i was intoxicated by the paint. So then later i was alright but then later that night i had all of the following symptoms;Confusion, difficulty breathing, strange behavior,extreme weakness, increased drowsiness, change in skin color, unusual sleepiness or weakness and i was really nervous and scared. I didn't really know why i was feeling all of this. So i went in my sisters room and told her i was really dizzy and i had trouble breathing. So i went outside and it was cold i took some fresh air. Then i found myself sitting on the couch in my living room scared and i was sweating, i had a rag and i felt like fainitng but I didn't. So my parents rushed me to the Er and i was diagnosed and they took my blood pressure and my iv and then i went home at 5 in the morning and i had school the next day but that night i couldn't go to sleep i was really dizzy and confused. So I stayed home from school that day because my doctor told me to stay home and drink a lot of fluids and rest and that if i could have someone by my side so i wouldn't feel alone and in case in needed help. So then after that day on Monday i wasn't feeling good anymore. I felt just like sunday night with all those symptoms and the whole time i needed someone by my side i was really scared. I don't know why but i just was. So i went to the Er and they diagnosed me again and took my blood pressure my dad had bought me some gatorade on the way to the hospital for energy because i felt really weak. So the doctor took a Ct scan of me and apparently the doctor thought that the syptoms i had might be due; because i was having some dizziness and shakiness of unclear cause. It certainly could be a mild concussion as we discussed, otherwise my lab Ct scan and exam were unremarkable. So according to all my diagnosis everything seemed to be alright but it still was not clear what was wrong with me. =/ All i want is for me to go back to the way i was happy and not confused i am really scared and i want this to be over with as soon as possible so i can go back to the way it used to be happy with all my friends at school. =/
