So... I've been thinking. I've had those periods. It wasn't all the time, though.
I just have one thing to tell you. Life is a gift. Everything around you, the life you're living. Yes it could get better, but it could be worse at any given point. Imagine what it is to die... will you disappear? Will you go to heaven? You won't know until you do die. I really don't think it's better than your life right now. So in such moments I take a break form my busy, tiring life. I've learned to care less and less for the things Id on;t want to care, and after I have that break, I've gathered enough strenth to go on living and change my life into better.
You want love?
That is easy, there are millions of people on earth, not all of them are assholes. Here's a piece of love for you to start off
^^ Search for it. I really hope you find it.
