I really do believe that people can be convinced by changing the meaning of the experiences that bother them to change how they feel about them. From my own experience I have went through a break up after 5 years of being in the relationship and before it has happened I was sure I will be devastated and depressed for a long time. However after it has happened I kept convincing myself that it is for the best, that everything happens for a reason and I may not see it yet, I also said to myself that it wasn't my decision since I'm not the one who gave up on it, so I shouldn't be sad about it and waste my time crying. Additionally I thought about all the hard work I should put into shaping my future and becoming independent, that gave me the motivation and distracted me from it, the more I had convinced myself to try to be happy and others around me, the more it had became real and I noticed that I'm genuinely happy. Not to mention that he realized he made a mistake and now tries to do everything he can to gain me back, yet I'm stronger now, I've learned a lot, I forgave but have not forgotten and I do believe that people deserve one last chance so... We will see how it will unfold... At least I'm not scared anymore.
