How to move beyond triggers and deal with root poblem

Hi, 

Trigger warning, 

Just trying to put down my thoughts and feelings.... 

I used to self harm about 7 years ago for around a year. I don't really remember the details. It was quite bad. It's always stayed with me. Even now when people see my scars and ask about them I don't know how to talk about it.

Somehow I managed to stop, I don't really remember how. Then I relapsed twice or so a few years ago but not fully because I couldn't stand the blood anymore. It didn't "help" me like it used to. I had learned other coping skills that stopped me from doing it. 

Over the last year or so I guess I felt like SH again. And I guess I did "different forms" (other than cutting) that aren't as noticeable and "less" harmful to the body. But still there was self-loathing and frustration and helplessness. I mostly manage to keep myself from doing anything most of those few times I feel like SH. 

But I realised that the triggers have changed, and I don't know how to deal with that. I don't know how to deal with difficult emotions and conflict especially those that involve other people.

I've found there is a deeper meaning behind the triggers and that there MUST be a way to resolve them.... I just haven't figured it out yet...
