You mentioned 3 things that everyone needs in their life; love, validation, and closeness, you should not feel bad for wanting these things at all. Also everyone varies in how much of these things that they need for themselves.

Have you tried just simply telling your therapist exactly these 3 things that you need?
Does this website give you anything you need?

Remember even a stranger can care about you, I know I do.

Have a good day and a great life, they are possible for you!
