If you have a plan don't easily give up just because of their words. It seems difficult while it also has chance to come true it.
Don't worry about the future. There are many factors that can infect it. So be patient. Learning to wait, and time will tell you how to deal with it.
Even if you walk the wrong way while it also has another ways to walk.
Don't harm yourself again. You need to understand you just have one person to care about you is yourself.
I hope you can have different choices rather than to limit yourself in a circle.
