runnergirl,

I think you need to slow down. The doctors are only clearing your physical condition. They have no idea about your ability to tolerate stress. You need to slowly build up your ability to function in more stimulating environments.

I suggest you focus on finding opportunities to tutor or work in small group settings. All of the voices in a classroom will be quite a strain.

Only you can know what is happening inside your head so only you can make informed decisions.

I understand your struggles and feeling of isolation. Been there, done that, doing that now after a recent relapse due to trauma and chaos.

My best to you..
