Hey Georgie, I agree in a way w/all stated above. However, what you choose to think about things and how you choose to feel is completely up to you! The easiest thing for you to do and hardest to conquer is letting your mind take control. Kind of hard to explain, but you/your body will 95% agree w/what your mind is telling it. Your mind is a very very powerful friend and enemy. How you choose mentally is up to you bro!
I went through my bullshit phase after a 11yr relationship w/my ex-wife and I was all f_ckededd up!! A man/mentor to me, talked to me over several different occasions about pyscological discipline. I didn't want to hear anything from him, but I finally did. I finally chose to quit letting my mind control me. The hardest part of it all is making the effort to try and let your mind think more positive. He told me to try and trick yourself in doing the things you once loved to do.
Well, sounds confusing, but anyone who has been really messed up mentally may understand.
It is important to not let yourself stop caring about yourself and others.
I probably would use this as a strength to cycle and get in the gym. Live there.
