Pretty much the same thing happened to me. I was bullied at Primary School, I still had some friends but they never defended me or anything. And they were always on and off with me. Some days we'd be friends and other days they'd stay away from me. I couldn't do anything about it but ignore it. I've always been too shy to stand up for myself, even now. I felt helpless but at the same time I didn't really have a lot of emotions then, I think I became numb after a while.
Had a slightly better time in High School though.
It's been easier for me to forget because I have such a bad memory so most of it is a blur now. And it was like over 10 years ago.
The bullies have probably moved on from it all by now, they might not even remember you, so why give them the satisfaction of remembering them? At least that's what I try to tell myself. I guess the memories and scars will still be there, you just have to try and put it all behind you.
Don't know what else to say, hope you're okay.
