I have been here a few months and I haven't seen this idea before.
I recommend that a lot of you lovely girls start a "to whom it may concern" letter/diary. I just started one and I feel like it helps to put my feelings to words. I am going to keep added to mine with new things or new thoughts. I feel like this helps. Especially if you're in the position where you're not out to anyone. A "to whom it may concern" letter/diary feels like you're spilling the beans about something with not actually telling someone about it.
Has anyone started their own diary to make themselves feel better?
