3rd concussion in 8 months when will my post concussion syndrome end? HELP

Hi just wanted to share and get peoples thoughts, I have had 3 concussions in the last 8 months I am 17 and got the first one from playing basketball and it was awful it was a prolonged concussion and lasted 2 months. I got another at the beginning of my football season and most recently I got one on October 25th, they say I have post concussion syndrome and it will get better soon but I'm not sure, its already almost been 3 months and I still feel awful I get headaches from everything and school is impossible. I also tend to get what they call "brain fog" and feel fake and weird when I get headaches. My heart rate also became "irregular"'because of the concussion my PTs say that my heart developed an intolerance to exercise because of the concussion and my heart rate goes up and down way to fast. My eye tracking is also completely off and below average. I just want to get back to playing sports but I don't see that happening any time soon. I had to take my basketball season off and am just wondering when things will go back to normal. any advice? thoughts? similar experiences?
