Hi all. I'm 20f, diagnosed maybe two months ago, and so far treatment's been going pretty well. 

However, the last week or so I've been on my own for the majority of the time (it's uni holidays but everyone else works) and I've gradually felt my mood and self-control spiral down more and more. Being alone tends to not be a good thing for me, and to make it worse my SO has been busy doing stuff with his friends and family (which I understand completely). However, without him to vent to or hug like I usually would, my mood has crashed to literally the worst in weeks, maybe months. 

I'm currently on a train by myself heading into the city, and I'm just filled with all these urges to hurt myself and feel pain and more or less fuck up my life - I want to binge drink, get a pack of cigarettes, pick a fight with a stranger, that sort of thing. Hell, the temptation is even there to get drunk and fuck a random stranger just to fill all the emptiness inside (although I absolutely wouldn't since I love my SO and would never cheat on him). 

My question is, what do you do when all your coping mechanisms are exhausted and those self-destructive urges are overwhelmingly strong? I'm trying to remember all the techniques I've learnt in DBT but it doesn't seem like enough right now :(
