This hits a little too close to home, tbh. Never getting that feeling of having a deep bond with anyone, except that one time, but then it turns into the most heartbreaking event in your life, I mean. Trust me when I tell you, that there's at least one other person who can relate to that in some way. <_<
Do you truly accept yourself? Sometimes I get the feeling that you actually don't. Even worse: it feels like you outright refuse yourself at times and may even reflect that onto other people.
Even if you may think otherwise: people want you here. But at the same time most of us are barely able to deal with our own problems. And even those who are better at managing their own life might be a little hesitant. Not because they don't like you, but because they're afraid; afraid that they may do something inappropriate, afraid that they could hurt you.
We ware no psychologists or therapists, we are all just oversized children who like talking about cute little critters that live in tiny balls. ^^"
I think you've said that PC is somewhat of a save haven for you. And I've also noticed that sometimes small fragments of your true personality shine through in your posts. It's those upbeat, full of energy, really cutesy posts that you sometimes make.
But I've also seen posts of you where every single word felt like you are crying out in pain. This happens every time when you start talking about your mental health problems. It feels like whenever one of these posts happen the save haven you found suddenly turns into a very hurtful place to you.
If you were to leave and were to look for a different place in hopes of finding another save haven: wouldn't the same happen there as well? Wouldn't you just be running away from yourself? Leaving behind those who truly want to know you?
We may all think differently and behave differently and some people may think and act in ways that no "normal" person could ever understand. But at least in one aspect do we all agree: we care about you and want only the best for you. But we want the best for _you_ and not for whoever else is trying to control you.
