Do you have a doctor and/or therapist? It might be helpful to consult a professional. I'm very familar with the way you are feeling. I've been battling depression for over 30 years. I know how empty it can leave a person. I did give up on life a couple of times and wound up in the hospital, with a change in medications thank goodness my mood lifted for a while. Most of the time it's tollerable but still leaves that empty feeling most of the time. I hope you can find the help you are looking for here and feel better soon.
