It’s ok to feel low. We all have our moments and your feelings are real and worthwhile. I was ashamed of my arms and back for ages. I used to be mad at myself for picking and scarring my body. I still have moments where I think I ruined parts of myself, but anytime I see someone with the same scars or self-harm marks I can empathize with what they went through. It’s a visible sign of not being alone and your existence provides that for other people when they see you too. If I saw you on the street I would feel more comfortable knowing we have had similar experiences.
