<human>: Give me the gist of the text in a nutshell

I used to harm myself a lot when I was younger. I was in fact still self-harming when I met him - which even resulted in us breaking up to give me a chance to work on myself (we'd been official for a couple months at that point). I did the whole therapy thing, and worked through most of my issues, learnt better ways to deal with it, etc. 

Him and I have been in a long distance relationship for the last 8 months, and will be until summer.

Yesterday I got some really bad news (charges were dropped against someone who did something bad against me), and I didn't really deal well.. I had a massive breakdown, worse than I've ever had, I think. It was seriously a crazy day. I just felt so helpless and alone, and like everyone in the world had abandoned me. 

Anyway, I ended up attacking my arm with some scissors, and I regret it a lot - I hadn't done anything like that for more than 4 years. 

Tomorrow I'll fly back home to talk to my old therapist and also my lawyer about what to do next, and my boyfriend is very excited to see me. But I'm really nervous, because I have no idea how he will react to my relapse, and I don't know how to go about letting him know - my first instinct would be to just try and hide it any way I could.
<bot>: Got bad news, self harmed for the first time in over 4 years. Going back home tomorrow, and will see long distance BF, worried about how he'll react.
