Im on my way to the cinema with my sister and I want to come out to her (she's 22) but I don't know if I should. I haven't come out to anyone yet, Im afraid I'll back out at the last minute.:icon_sad:
Yes, just do it. I've learned that the build-up and anticipation of telling someone is worse than the actual act of telling them. You'll be so relieved after you do.
If you've decided that you want to tell her then you've think about it enough to do it! Go for it! Good Luck!
