I understand that what you want is a treating person, who is professionally just for you during your time. And you are right, in normal life and in support groups etc. it is reciprocal. At times the other party can give or take more, but in general the relationship supports both/all parties. Maybe you should try if you are capable of a regular relashionship, even a friendship? A good start could be a support group, volunteering etc. Maybe your are has an fb-group where people can ask for company for walks or such.
