About 2 years ago, I happened to go through a break up. I was going through a pretty tough time in my life where I completely lost myself.
I distanced myself from family and friends and believed that I was able to handle everything on my own. I believed that I didn't need help. I kept everything inside and bottled up until eventually it would overflow. The anger. The sadness. The regret.
Whatever happened, I would blame myself and nobody else. In the beginning I never blamed him because I thought that it was because of me that drove him to this decision. But eventually all the negative feelings I had towards myself were redirected into his direction.
In the process of healing, I constantly reminded myself that I would be okay and that I deserved better. I showered myself with positivity and eventually the anger I bottled up within melted. I was no longer angry. I was no longer filled with rage and misery. I was free.
What really opened my eyes was what a member of the same discussion group as me had said which really gave me a whole different perspective of the issue was that "why should I suffer when he was the one who broke up with me? He should be the one suffering."
So in summary, yes, I do believe that by changing the meaning of the experiences that bother you can help you feel better. Positivity is always key.
