"Today was a terrible day because..."

[Cleobel]

Since last week, I’ve been feeling terrible because one of my friends has a big problem and it’s all my fault. I didn’t intend to cause this problem, I just made a big mistake. I apologised as soon as I could, and I did my best to help him solve the problem, but I couldn’t do much and the problem hasn’t been solved yet (otherwise, I wouldn’t be posting here). My friend said that he is not angry at me, but I still feel very guilty and angry at myself. Even when I play Pokemon, I feel guilty because I think I don’t deserve to do it. I don’t know what you think about it, but maybe my friends (in real life and online) would be happier without me.
