you should do things that make you feel good, focus on positive things and not so much negative. heartbreak and depression isn't something you can just get over, hmu if you need any help or need someone to talk to !!
That's a very touching story, and you are right. There IS always a solution to be found for every problem. At the time it never seems that way, but as you quite rightly say, tolerance increases, you develop greater inner strength and as you grow as a person bad things become easier to grasp, comprehend and climb over and deal with.
