I’ve been feeling suicidal since when I was 15 years old until now

So I’ve been suicidal it’s because of my anger issues and craziness, I really don’t know how to handle it, it feels like life is against me and everyone is better than me, that’s how I feel, I’m sixteen and I still feel like that, especially from things that are small and not worth it too, it feels like something is wrong with me or just I take almost everything seriously, I hope I get good advices in the comments (16M)

I’m deeply sorry if my message is uncomfortable but right now I’m safe, please I hope I get comments because my last post was empty, I’ve been in therapy session before and I guess nothing changed, I tried, I tried so hard to change and when I’ve been 16 I thought I’m free, but I guess I’m not.
