@killyourfm I couldn't agree more with your friend. Trust the healing process. Everything will make sense in the end.
I also have my struggles, as a schizophrenic, but I have never lost my faith in the Universe/humanity/call it what you will.
Don't overthink things, focus on your blessings and everything you've accomplished.
Everything is a state of mind. Keep calm and appreciate what the world has to offer.
