The choice is yours to make.
When life seems to keep handing you bad things or your surrounded by people who seem to always be doing you wrong it's totally up to you what you do with the feelings your left dwelling with.
You can let the bad make you or let the bad show you what you don't want to be.
You can have any kind of thoughts, but you are in control of your own actions.
One way to start on your journey out of bad ideas and thoughts is by doing good or nice little things for others.
It makes you feel good. When you feel good you begin to have good thoughts. Each good thought pushes the bad thoughts further away from your mind.
When you do good for others they smile and tend to like you. Your making better friends.
You can try helping neighbors. Try helping people you see who need help in stores. Try volunteering. Even a simple shared smile can start you on your journey to being a happier person. There are many very lonely people out there who would cherish a few words shared in passing.
The trip out of your own sadness can simply start with you attempting to make others happy.
Happy is contagious.
