Not Loving yourself.

I'm just not happy with myself. I don't love myself I guess you could say. have any of you gone through this issue and how did you change that feeling? Im feeling depressed because of it lately. like im not good enough for my SO nor my son. Like they would be better off without me. I don't think im pretty I dont love myself. I think im fucking fat and ugly and gross. I just feel sad all the time
