I too, often feel the same way as you. So many people care for me and tell me I'm important, but all I see myself as is worthless and a failure. The depression is a vicious cycle. I also have the rollacoaster days, weeks where some are good and some are bad. All I can say is make sure you have a plan have a good therapist and maybe sign yourself up for groups. When I was going I was attending DBT groups and when I was utilizing the skills I could at times help regulate my emotions. And, I was feeling a lot better about myself. I hope you feel better.
