Algebra 2

I don't know what to do. I talked to my math teacher about my grade (I'm failing) and she said that I just have to keep trying and staying after for tutoring and do everything I'm doing now. She knows I'm trying my hardest. I just wish I could know if I'm going to pass or not so I know what to do and if what I'm doing helps (I mean, it doesn't, because I stay after nearly every day and it doesn't do shit, but idk maybe if I torture myself enough she'll bump my grade up at the end, idk. I know I'm going to fail. I can't do it. I'm trying my hardest and I can still never understand math and I have no idea why because everyone else gets it and passes their tests and then there's me like it always fucking is, in the back saying over and over "I don't get it". I wish I could feel worth while.
