I believe you are strong, when you really have true faith In Jesus, because thru that you get true faith on yourself! Now some will argue that is because people need to believe in something? And to that I would say, you can't take away a feeling you were born with! Nobody ever had to brain wash me about God! It was always someone that walked with Me!! You are also strong! When strong is all you are left with..
Take risk and go for what you want in life and take chances and try your best to get threw stuff on your own or doing stuff more independently then relying on anyone else for help or guidance and find stuff that helps you on staying strong emotionally wise like a hobbie or something that keeps your mind off the bad hope that helps
Fake it till you make it. Then you look at where you were and you see that doing that has allowed you to get tough in some new places. Then you look at where you are going and realize that you feel tougher than you were. Then you will feel okay with putting your other foot forward, so you can get ready for your next life challenge.
