Memory lose

I don't know what to do I can't remember my childhood or high-school I think it's from my head trauma in high school ( Concussion ). My friends and family keep telling me things about my self that I don't remember I feel like it's my whole life I forgot, I can't remember a lot of basics i feel like i have to relearn how to live entirely. I've been bed ridden for 2 maybe 3 months. I'm slowly recovering i can finally kinda walk normally. im 22 I don't know what to do I'm kinda scared and anxious help.
