Hi Lexxinski, sorry you are feeling anxiety over making friends. Why not tell these people your feelings up front and maybe they will just cancel because what you want and what they want is not the same. There is no shame in that.
Whatever your sexual preference, including not interested in sex, looking for online ads does not sound like the right approach. Most online ads, people are looking for physical affection and not just friendship.
You are doing things to try to socialize not prove your prowess in bed. I think your therapist has the right idea look for friends, but I don't agree that online ads are the best way to find them.
Other lifestyle changes that help me are doing yoga, exercises, mindfulness, calm music, and being active on Psych Central. All of these have been sources of friends but it takes time.
Glad you are joining us here. There are lots of compassionate people here that can make the load lighter by sharing and caring. Feel free to participate actively at Psych Central.
