I've never felt so shit

[EssentialAspiration]

My life is going to shit and I don't know what to do. I fucking hate school, it's nearly over, two months left but I feel like I've fucked that up. I'm in a relationship with a beautiful girl who I love that has absolutely no intimacy because I'm too scared to do anything. I'm generally just a fucking failure and I have no future. I'm 15 years old and life is just getting worse. Nothing is getting better. Things get harder, people expect more and I'm just so tired. My self confidence is at an all time low and I hate myself. Which is probably why I'm so socially anxious but I've always hidden it with the whole fake confidence thing and it worked so well. But then I just had to go and get in a relationship and now I'm too much of a coward to take it any further but too in love to throw it away. I am fucking ruining anything and I don't know how to deal with this
Does anybody have any advice?

Hi , I'm sure it's just a ruff patch, your under a lot of pressure at school, take a deep breath and slowly breath out. I found school hard and that's even after repeating a year, I understand the fake confidence, I've used it for years. With your gf I know how it is to love her but being to nervous to take the next step. I really regret that i didn't take it to the next level, we ended up on a break , but we both knew it was over. Just remember like you said 2 months of school, it will go fast then you don't have to worry about it. With your gf tell her how you feel, otherwise she won't know. Message me if you want to talk more, it's harder having the girl you love talking to you but not wanting a relationship, it kills me.

People always expect more when they can't deliver themselves. Just be yourself. If you think that you're enough, then you are. Simple as that. You are the one in control of your life.

This advice is definitely not for everyone, but think about it this way: you're only 15. We both know that this is not your last and only relationship. There will be many more to come. So give it your all, like it actually is your last and only relationship. Don't be afraid of making mistakes. Humanity would not get anywhere without mistakes. Mistakes are the best teachers. I know this is easy to say and harder to actually do. But please, believe in yourself :)
About making another step in your relationship. Try being more physical. Hug her more often, kiss (if you do that) and I'm sure she'll get the hint. Say that you think all the time about her.
