The Internet is such a skewed place, riddled with double standards. Everyone is expected to share the good times with all and sundry, but when you're in pain and deeply hurting, you're expected to just shut up and not tell a soul; there's no place for you.
You're not wrong. It's why I primarily try to stick to having conversations on Twitter, or posting interesting facts, or things that I figure the nerdy folks who follow me might actually enjoy. Personal lives and social media are like oil and water.
