I didn't really want to go but I know it's good to get out so I went to a co-workers annual bash (I had never been before)
I promised my self I would stay at least 1.5 hours which was a little difficult as I only knew her at the party, but chatted with a few other people, and milled around, great food and some brought out their guitars. Then another coworker arrived so we chatted easily, I made it to 2 hours before I left.
As soon as I was on the sidewalk I started balling .....
I just feel like I'll be alone for the rest of my life, with no-one to share the little things in life. And while I'm actually okay with that, it just hurts now since it's a transition from a couple to being alone.

Re: went to my first party alone....
Good for you that you went! I completely understand how awkward it feels when you go to something by yourself and only know 1 or 2 people there. I have a really hard time making conversation with people because I'm super shy until I get to know people. But its one of those necessary evils if I ever want to expand my friend circle. And, I don't know about you, but I've found that my friends that have invited me to stuff like have some amazing people in their life so I'm meeting some really great people!
The feeling like you are going to be alone for ever will eventually get better. It just takes some time and it will eventually not matter as much. Just remember its better to be out there alone than with a crappy partner
Props to you for going! I find myself doing the same thing. I would rather stay home and avoid the awkwardness, but force myself to get out whenever I can.
Baby steps right?
Good for you, you will get used to this.
Even if it takes a while to meet Mr. Right, you'll slowly start feeling better about doing things solo, and you won't think about it as much. It just takes time to feel comfortable.
That's a good milestone! I do the same thing ... I'm usually the last person to arrive and the first person to leave, but I always make myself stay at least 90 minutes (and I don't get invited to many parties. I am never at a party where I don't know some people).
It does get easier with practice, I promise! I still don't love going to parties, but it does not always suck. How's that for a ringing endorsement?
