trust no one but yourself!

Have you ever sat and thought? who actually are my real friends, should I trust them?
I'm at that stage at the moment, everyone seems to be just stabbing me in the back at the moment.. I may not show it but it hurts, hurts worse than a bee sting on the lip. To be honest, I don't even know what to say anymore, I wish I had it easy like I used to. I wish I never had to constantly worry. I wish I had my old life back.
Will I ever be able to have my life back into a healthy shape?
