dolce,
I'm not a counselor, but, it seems to me that these issues are connected.
Your parents are alcoholic and you have no relationships.
Those patters were set up early in life.
For example, was it embarrassing or hurtful for you to bring people home as a child?
Where you afraid of what your parents would say or do in a drunken state in front of childhood friends?
Or alternatively, where you not allowed to brings friends home as a child?
I think you *do* need to bring these issues up with your counselor. It's not about embarrassment. It's about getting to the root of your core problem. This is hurting you. It's interfering with the quality of your life. And that is exactly why we see counselors. Please do dig deeper and find the answers. A better quality of life awaits you.
Shalom!
