Personally I think it is not only a waste of time, but actually futile to try to ‘fool’ yourself into thinking that something is alright, or that you’re happy when you’re really not. Negative self talk comes with a reason, and as a result I try to figure out why I’m bringing up the negative points to begin with. Basically I try to fight negative thoughts by evaluating myself, my likes, my wants, my needs, my preferences, etc and determining what my strong and weak points are, and how I’ll react to the situations in front of me.
Sometimes it is other people’s fault why we feel low or have bad things happen to us, so the key is not to blame ourselves for everything. The key is to be honest, and admit it when you are in the wrong yourself. However there are times when a bad situation isn’t your fault, and it is during these times (and more than ever) that we need to stop blaming ourselves. I’m not great at doing all of this myself, but it is something.
