Do you have faith in a higher power? That's my go to for fighting anxiety and sadness. I know I am going to disappoint myself, other people are going to disappoint me but it's okay. I can find happiness in any circumstance if I really want to. Everything is what it is, the only thing I can control is the way i'm going to look at it. I hope you learned to love yourself. There is always someone else would be grateful to be you.
