I know things are really hard right now. But you DON'T deserve a guy who would leave you after 6 years and get married to someone else within the month.
You deserve much better than to be crying in bed all day. Please wake up to the reality that life is much much more than one relationship, no matter how much it may seem like it. There are plenty of other meaningful things in your life such as your work, family and friends. Most of all, there's YOU.
Please do take care of yourself. Don't take yourself too seriously. The world hasn't ended. Please feel free to talk to me whenever you feel alone and need support.
