crying in bathrooms

I have pretty much been crying in public restrooms for as long as I can remember. My former roommate is currently an RA in the dorms we used to live in first year; when I used the restroom the smell of the air freshener sent me straight back to my first year and I my first memories were not of joking around with my friends as we got ready for bed or left the showers, but was of me crying in the stalls. When I was in therapy I cried after just about every session and the first place I zipped to once I left the office was the bathroom downstairs. Crying in public almost became normal for me.
