Hi Mia,
Sorry to hear about your situation honey... I can imagine it can't be easy!!
I'm 24 and in a bit of a situation where my boyfriend (or shall I say 'ex') also needs space. He suffers with anxiety, depression and panic attacks so I've seen how difficult situations can get. On the first hand, I feel completely frustrated and helpless and 'in a rut' as to what to do, but what I've worked out for myself in the long run is that if a guy needs space, you have to give it to him. I know my situation is probably completely different to yours, but with my 'guy', if he needs space, I have to give it to him otherwise he runs a mile!!! When his head is in the current state that it is, I know I can't put too much pressure on him; it only seems to make things worse. It's soooo frustrating and the separation between us at the moment has been the longest it's ever been, but I do feel that once he's sorted his head out, he'll come back around. I know it's hard and it's so painful when you really love somebody, but perhaps try what I'm doing which is do your own thing for a while. We're both so young

Why don't you concentrate on yourself a bit more, go out with friends, etc and when he's ready, I'm sure he'll come back to you. If he loves you, he will want to talk to you eventually, be it take a day, a week or two months and whether or not it's for the relationship to keep going or end (if that makes sense? I'm hopeless at typing really

) It may be that all he needs is time to sort out his head and maybe the reason he hasn't contacted you yet is because he cannot deal with the intensity of a relationship, as well as the problems he is having to face at the moment.
I know my advice might not be the best, but it could be something to consider. And how about we keep each other posted with what's going on? It's nice to know that there are people out there in very similar situations and I'd like to hear what happens
Take care and I wish you all the luck in the world!
Steph
