A list of things I believe about vulnerability, intimacy, boundaries, and Twitter:
1) Some parts of your inner life are fragile. Others are sacred. Others you simply prefer to keep to yourself. All are good reasons for privacy.
2) Most things are better shared. Sharing your inner life with people can "double your joys and halve your sorrows".
3) Intimacy and commitment belong together. It's really good and healthy to share private parts of your inner life with people who will be in your life forever. It can be scary to show them more of who you are, but it's rewarding to have people who are committed to the real you.
4) Because some parts of you are fragile or sacred, think carefully before sharing your innermost thoughts and desires and secrets with someone you just met.
You can end up easily manipulated or hurt. It's the emotional version of hook-up culture. Be safe.

5) Some people feel like they can't talk to anyone about their innermost thoughts and feelings so they use Twitter to cope. They DM things to strangers they wouldn't dare say to their loved ones and fave others' confessions.
6) Some people find one sympathetic ear and unload every secret thought on that one person. This can result in their sympathetic listener pulling away.

7) To build emotional intimacy and share private thoughts and feelings in a more committed context generally involves trading slightly more intimate details over time. The 36 questions to fall in love with this way. http://36questionsinlove.com/
8) It's maybe good to treat friendships a bit more like romantic relationships? Occasionally talking about what you're looking for, working through conflict, breaking things off if you can't make it work rather than ghosting the person who shared their inner world with you.
9) It's definitely good not to share intimate details with everyone who asks for them. Some people feel entitled to your inner life; they are not entitled. You get to make the call about who really knows you.
10) Ideally, as you love and trust yourself more, your boundaries won't be based on fear that other people can't accept you - they'll be based on love for all the cool stuff that's still cooking in your brain.
