Memory loss

I've been experiencing this issue lately that's overtaking my life and I just need some advice, I'm hoping maybe others experience this and know what I'm going through. I used to have the best memory as a child, I would remember the words to every song after hearing it once, I'd remember ridiculous strings of numbers for fun, I'd memorize quotes, etc. but ever since I was about 16, the time when I had to remove myself from my abusive household, I've had trouble remembering nearly everything short term. I had a bad issue of blocking out and refusing to accept my trauma, but I believed that I'd worked through that since I've been away. I'm 19 now and I find that whenever I'm having a conversation I can't remember the names of people or words that would usually come up so casually, I also find that I get disoriented and confused easily. I've noticed that when I feel anxious I kind of blackout a little bit, I feel much less cognisant and kind of like I'm watching myself react to things rather than have any control. Any advice as to what I should do? Or if this is normal?
