Physically ... nothing yet. I look so much like a guy right now that dressing feminine or anything just seems to underline my dysphoria. It feels nice to wear those clothes, but then I look in the mirror and just get even more depressed ... so I'll definitely keep from doing that for a while.
Mentally though, I love watching a stereotype girly movie (Bridgit Jones or Love, Actually come to mind) whilst being snuggled up in my blanket and having some ice cream. It's about as stereotype girly as you can get, but I just love doing that. It's the most comfortable feeling ever.
