You are not too far gone.

In my opinion, a good therapist for you will have experience working with people who are dealing with issues of attachment, intimacy, and abandonment. If they have such experience, and if they are good therapists, they won't say such things as you quoted. Instead, they will help you talk about and explore and better understand whatever happened in your background that has given rise to the difficulties you are facing. When you have a better understanding of what went wrong, it will (in my opinion) become easier to deal with and accept intimacy and attachment from others.
