What i'm about to say is going to hurt but you are never going to get those particular needs met by your T or any therapist. Even if you move to a therapist who does hold your hand or hug... they still can never be your mother, they can never look after you outside of therapeutic relationship. Than yearning you have is perfectly natural and understandable if you've never had adequate mothering, however you are chasing a dream that you'll never get, definitely not from a therapist. The reason that need is getting worse instead of better in therapy is because you are continuing to to chap on a door that will never be opened to you. Your inner child feels like it's constantly asking mommy to hug her and getting denied.
The only way forward is to face the grief that you need to do over what you didn't get in childhood and the acceptance that the time for a "mommy" is over, you didn't get it, and there are no "do-overs" in adulthood and that hurts- a lot!

If you can get to that place where you realise no other adult can meet the young needs you have inside and that you got neglected as a child then you can begin to grieve for it, grieve for yourself, and eventually find acceptance and then peace.

I'm just at the beginning of that journey, for all my life i've looked for someone to look after me because it meant i could avoid facing up to the true cost of not getting remotely good enough mothering. And the cost is massive, overwhelmingly so. I've wanted to accept that i no longer am of the age where people will want to mother me, there is no "other mother", only the one i had who did a piss-poor job of it. But in constantly looking for someone to be my mom, i was delaying healing. Avoiding the heartbreak that is to come. And it was really hurting me. It's only in the past month that something really clicked in me and i realised i had to quit the dream of finding a new mother and start doing it for myself and surprisingly i've found some peace in that acceptance. Now starts the grief work.

Sorry for the essay, i hope it's of some help.
