anyone else struggle with showing affection?

I really want to show affection and tell them i love them, but it’s really hard to get out. it even feels like my throat is closing making me physically unable to speak my affection. I struggle with showing affection through touch too.

Though i crave affection and love, it's incredibly hard for me to show it and i just dont know why. I just came to be self aware about this recently. Can therapy help or is there someone who has struggled with this before?
