I'm not sure I can add much to what the others have said....
There are times when we all just need to vent a huge amount of emotions and in those moments we can fell like the whole world is falling apart no matter what we do. Sometimes it is just best to let it fall apart, let yourself fall apart and then when you are done venting, pick yourself up and start again anew. There are lots of sayings along the lines of 'Everybody falls, it is getting back up that shows what your made of.' Besides for me these are some of my happies times (I'm weird! ) because you can learn a lot about yourself and after the storm has passed everything is just a little bit sweeter, brighter and more fun.
Sometimes being alone does just suck but using someone to fill in a hole in your soul (or whatever) doesn't work for long. I know what it is like to look for someone else to accept you for who you are instead of just accepting yourself as you are. I'd rather be alone than in a bad relationship, but if you don't put yourself out there, vulnerable, fragile and ready to be hurt, how can you ever find true love. Still if you arn't completely comfortable with yourself then how can you expect anyone else to be?
Jamie, your an amazing person.....and I don't even know you that well! I hope you find confidence in the person you are when everything else has crumbled away.
