I read your whole post, and I feel like I have an idea of the place you're in. I am a bit older now, but here's something that happened to me... when I was in my late 20's I had been in a relationship with this guy for a few years and we got engaged. When we met I was totally in love with him so I thought he was "the one." He had good opportunity if he would move for work so he did, and the plan was we would do the long-distance thing for a few months until I could get a job where he was and then get married. Long story short, I was over a thousand miles away when I found out through a third party, that he was cheating on me and had lied to me. My whole world went into a tailspin, I was in such a state of shock and panic it was a lot like getting news that someone I knew was dead. When I called him he admitted it, and more! It was almost too much to take. Devastated might be an understatement. I decided I had to end it so I did and he sent me a letter or two and a call or two begging me to come back. It took a few months, and then I realized I was already over him! All it took was getting in touch with my anger at him, I was in love with the idea I had found "the one" and didn't need to keep looking... I was not in love with him, he was a liar and a pig. Around a year later I met my husband, who is around a million times better suited for me. A relationship is nothing without trust.

It will suck for a while, and then life will get better. You will meet someone else, and I could almost guarantee they will be better. You need to just focus on you and finding things that make you happy because worshiping a liar is a recipe for disaster... and well honestly, worshiping any one person above all else is usually not a good idea too. Sorry you're suffering now, to minimize it I suggest going out and doing things even though you don't want to, seeing friends, talking to people, rallying support around you to whatever extent you can. If you feel totally alone don't worry though, I was totally alone and I survived.
