My trauma isn’t valid tw: ea, Covid, suicide

So I’m 16. I’m living at home. I was emotionally abused and emotionally neglected my entire life. My sister was the only parent and she’s two years older than me so she was a kid. It wasn’t right. There was no malicious motivation, they just never learned to love. My parents have also been fighting my entire life, not physically tho so it’s not domestic violence (Except for the year of Covid- surprisingly that was good for us). I found out smtg disturbing abt smo close to me so I got put into therapy (Thank god!) I attempted suicide. Now my mother is like there? It’s rlly weird and I feel like because she’s trying now it doesn’t matter that she was mean before. Also I have friends that their parents scream every day and my parents only fought like once a week - when we’re all together. So like their not even fighting that much so I shldnt b upset!! But I x have a normal childhood cuz I moved when my parents where fighting and I ended up disassociating like crazy so I x think this world was real. But that’s not anyone else’s fault but mine. Nobody did anything wrong to me I was just born messed up.
