From your other posts, I think that social anxiety has been a barrier to you connecting with people for some years, but you are already forming a good bond with your T.

Suppose you think of it this way? You've recently made a good, authentic connection where you've been brave enough to be yourself. Sure he's a T, and every relationship is different, but this authenticity you have with him is a beginning. If the social anxiety lessens and you're more able to be yourself, you're sure to develop more such authentic relationships. So it's not only your T that is giving you a reason to live, but that he represents the prospects for a more connected life in the future.

I would also note that you're making connections here.
