Heartbroken and lonely

Never had I open up emotionally to someone. The one time I did, it just bit me in the ass to remind me of how much I should not share so much or not at all. It is the hardest relationship to get over. This is taking too long. Since there is no turning back, I don't see why I cant just walk out of this phase I am going through. If there was a second chance, I doubt I will ever allow myself into that ditch again. I am emotionally drained and tired. Sick of all this emotional play and do not wish to dwell into it for the next few months or years or however long it takes until I gain the strength and will to control it all over again. Emo bastards are people we don't want to go near. I've had enough.
