Hello all, I'm new here (20yo) and this is my story

It all started 3-4 month ago,
when I practiced an acrobatic move (handspring) in which my legs hit the ground in locked state, very forcefully, so my head and neck have suffered the most,
I was dazed and saw stars(litte dots floating) for a minute, then I was stupid enough to do the move over and over again.
I felt very bad, my neck was very painful, felt jolts in my neck.
Later, I felt fine in few minutes so I forgot about it.

Following day I had this weird headache that doesn't go away.

In the first weeks I had difficulty looking at bright objects in addition to the headache.
I feared I might be losing my eyesight and was scared.

By that time, I didn't know anything about PCS or even a concussion.

Past 4 months I had difficulty with concentration and vision.
The headaches are the main issue though, especially behind the eyes,
Along with nausea that triggered by studying and reading.
Things got little better,

But for no obvious reason I had many setbacks and the headaches changed to tension headache, and eye strain.

Noticed many symptoms, difficulty concentrating, eye strain, nausea, anxiety, something room spinning when I lay down, but the most persistent is headaches that Changes in frequency and location.


The headaches went on a daily basis, even though I have good days sometimes even a week.
A month ago my doctor sent me to neurologist then I did cat scan that came normal.
I had to quit my studies and now Im at loss, no diagnosis, severe anxiety, tension headache.
Did i get PCS, or maybe i am loosing my mind?
Any help is appreciated
