Dear CIB sorry for the hard time you are having, I have suffered from loss of hearing my whole life i probably should have had a hearing aid since i was a kid but my father frowned on anything that would make me look different even if it was for my benefit, i finally wised up and got one about 10 or so years ago and it has made an incredible difference, anyhow getting back to the issue of friends it is very hard to form and keep friendships when you suffer from low self esteem like i did for most of my life and yes therapy can help with that very much and if you really cant trust your therapist then you need to stop going to her you need a person who you can trust completely your parents may be signing the checks but she is YOUR therapist not theirs.
For others to have a positive view of you, you have to have a positive view of yourself and trust me it is not easy, just know that you are a special person that has value and you were given the gift of life because Hakadosh Baruch Hu wanted you to, you have talents and qualities that make you special focus on what gives you joy and learn that you deserve friendship and all the good things life has to offer. Hatzlacha.
