Likely: Life often gives us challenges we do not have the skills to fix. You wouldn't try to fix your bad appendix & you shouldn't try to fix this alone. Find a life coach/therapist to assess you and begin training you in ways to get past this. Your doc should know of a local person that can help. Meds may be needed to speed the process. Do the work & life can be better, if not you are stuck where you are
