Social anxiety

So we’re pretty much all afraid of talking and meeting people. Seems majority of the system doesn’t want to get out of our comfort zone with expanding our social circle. We have 1 part who’s consistently trying or 4 maybe, at least 3 with girls and 1 with friends. We’re single and want another safe person but the process of getting to feel safe with another person is so damn long and we’re scared to go and try to get there with a new person. We have 1 rn outside of therapist and then we mostly feel terrible bc of lacking social experiences and time to be out around someone else. Has anyone successfully had their whole/majority of their system on board to do this? If so how? We’re not sure if we’re going to but want to hear some experience and feedback on this
