There will be those out there who care for you, if not already, those who you can and will form those bonds with.
You may even never know it: a friend's former boyfriend who I met once, a year later had a chat with me on Facebook and had incredibly gushing things to say towards me. Perhaps gushing isn't a respectful enough word, but... Anyway, we've only had a few chats since but he's confided in me some extremely important things. There are several other people who I could approach with troubles I'd hide from absolutely anyone else at all costs. Generally they couldn't be bothered with my interests, even if they bring me the deepest of emotions, but those emotions themselves, and my backstories, hold-ups etc, they'll hear about or help with. I'd like to think they'd remain if I grew to be more cumbersome but there would be only one true way of finding out. This isn't intended to be a brag, rather a reassurance that you can find these people. I have confidence that a real load of people, at least in western society, lack this sort of intimacy with anyone, but it's worth nurturing as well as growing together, as assurance and fidelity can be taught in relationships.
We've all been there. All de best.
