Hi everyone,

I don't really have anyone to talk to about what is going on in my life right now, but I need some advice on how to keep my head on straight with everything that is going on.

Some background:

Earlier this year in April my fiance broke things off with me, pretty much completely out of nowhere. We had been together for 4 years and I proposed in February. She continually tells me I did nothing wrong in the relationship, but that almost makes it worse that I am losing her and essentially nothing I have done is the cause. It seems like there is nothing I could do to rectify the situation. She is moving to Arizona and its pretty likely that things aren't going to work out for us.

Then, I got news shortly after that that my best friend [22M] is joining the airforce. I am happy for him, and I know this is something he wants to do and I think it will be awesome for him. I just wish it wasn't at a time in my life where I desperately need someone to talk to. I wont be in contact with him for close to 3 months.

On top of that, one of my long time friends and co-best friend [23M] has decided that him and his fiance are moving to minnesota to be closer to her family and so that he can find work after his graduation this year. He leaves the 12th and though I can talk to him on the phone, he is really preoccupied with all of the things going on in his life right now. 

So essentially the 3 people that I care about most in my entire life are gone all at once. I have nobody else to talk to and for the first time in my life I feel really alone and I am having a lot of trouble wrapping my head around what to do. I don't really know how to meet new people.
<bot>: Everyone I have ever cared about is leaving within the span of 2 weeks and I don't know how to handle it.
