You know that phrase 'don't kid yourself'? I think that's what I do.

I kid myself that things are going to happen. That I am going to have a relationship with T, that I'm going to move forward and live happily ever after. None of it seems possible, let alone likely.

I think that is called positive thinking. Have you told your T that you feel you don't have a relationship with her? Sometimes you gotta be proactive as well as hopeful. That means telling people like your T how you feel. I know some of them seem like they know what you are feeling but they still can't read your mind. Also it could be a bad fit.

Hi Illegal, not so dismissive about the "moving forward" bit, hey??!!
Sometimes it can feel like nothing is going to change, things just keep getting harder or at times you're more moving backwards than forwards but that doesn't need to say that you can't/won't move forwards. It can sometimes be a real struggle to move on, sometimes we have to ride out real tough times, sometimes it can take time but............
And you know you might need to try different things at times or need more help/support at times.............but don't give up on that one hey??
As for living happily ever after, I'll reserve judgement on that . Not sure how many people actually do get to "live happily ever after", but if not then that doesn't mean to say you can't have an enjoyable; really notable, fulfilling, meaningful.............life.
But other things that might not happen (from other posts you're meaning a "romantic" relationship with your T??) I'd say it's not so much about trying to dismiss/let go of some of those hopes but maybe more about refocusing them on positive things you can more realistically work towards??? Things you can have a real strong influence in. And some of those things can have just as important/meaningful an impact on you.
For example: instead of the relationship maybe focus on how well you and your T can work towards helping you with some of the things you want from therapy?? Afterall it sounds like you feel a real rapport (?) with her...........so maybe use that, just use it in a different direction??
