Sarah, I'm hearing from other 20 and 30 something here whom I like and admire that they're experiencing the same things you do. Here's my hope for all the 20 and 30somethings who are especially sensitive people, who are HURT by neglect and personal jibes from others: I get it, I was in your shoes. I ran for years, first from my own family of origin and then out into a calloused world, from job to job and ultimately never comfortable with community, always looking for a place to accept me, always hopeless, knowing there was no place that would accept me, that there was something WRONG with me. But, we are NOT over-sensitive, we are PROPERLY sensitive. We are the ones who get it RIGHT.
At 40 my partner died but before he died he gave me a gift, unconditional love. What I learned from him is that the WORLD is a fucked up place, there was nothing wrong with me except that I internalized all of the world's meanness as if I was the problem.
It's not about getting hard or calloused yourself. It's about embracing who you are as a sensitive person, loving yourself and accepting yourself and learning to hold your own ground while you learn to walk your walk and talk your talk, give to others as you become stronger. The WORLD is a fucked up place. We are not.
My hope for 20s and 30s who are sensitive is that you let your sensitive you float to the surface and prevail. We are the ones who have a vision for a kindler, gentler future, more thoughtful. I've learned to elbow self-aggrandizers out of the way, prejudice out of the way. I've learned to stand my ground while being an advocate for others.
Give yourself the unconditional love you can't find in this truly insane world. And try not to run. Every community will be the same. Here you can grow and change and adapt in ways that are effective. But, love your core, don't give up on your core YOU.
Me on a soapbox sharing my experience!

I for one hope you stay

When you're cut, we bleed. Happy for you when the news is good, sad for you when it's not.

Please reconsider leaving. Ignore the ignorant and focus on the positive. If there are other sites that you belong to that are stressful, delete them. I can help you if you want. I am a great listener.

I'm so sorry you're experiencing this. Many of us want to see you prosper.

You need to be who you are. To hell with anyone that doesn’t like it.

Stay on the site and just block the asshats. I love how open you are. I wish I could put my self out there like you do

Personally, I love how you post openly and freely about your situations, while working things through. To me, that's being a twenty to thirty something who's trying to make sense of the world. You are genuine and without bullshit or ulterior motives. I don't always read, but, I ALWAYS think 'there's roo, fighting the good fight'.
Take the nuggets that are useful and discard the others. Some comments are not meant to offend and posters might not realize you are vulnerable. You could start your posts with 'feeling vulnerable about this' and 'useful and supportive comments only please'. Then ignore anything that isn't. Just remember that when you make public what you're feeling/thinking, you open the door to comment.
Have you thought about posting to the mental health forums until you feel more 'emotionally strong'? You might get better support there.
ALSO grow with each post. Internalize the helpful comments, learn from them, become less dependent on what others say. HUGS!

The internet is full of trolls. People who can remain anonymous and attack others only because they can Not because they have any good alternative points to make. I haven't been seeing that on this site but I sure see it on alot of other ones including facebook.

You raise an interesting point (can the be raised?). Over the years I wrote to several news papers asking people to concentrate on issues rather than attacking the promoter of a different viewpoint. Unfortuately our culture is cobbled together by those who find it easier to undermine people's credibility rather than knitting a good argument. Just don't worry!!!

Just block these people, don't leave

You are never going to be without judgement. please only yourself. If you are happy here, by all means stay.
