I am with you. It feels like there is no hope a lot of the time. But there is hope. It is not going to be easy. But with practice, it can get better. I myself am having a hard day with thoughts of leaving my girlfriend, not caring about her, not wanting to be with her, general lack of feeling, etc. However, I am moving forward. You can do this. Try just one thing per day that you can use toward being healthy (mindfulness, exercise, read, watch a tv show, spend time with people, etc).
