Since I have also tried a lot of treatments over the years (medicine/psychiatrist). I think I can also offer you some good personal advice on what these things are like and if they would work for you.
All my gigs are very personal, if it says 2 hours, then we also talk for 2 hours straight, if you respond back ofcourse lol. But I certainly will answer all your messages and emails directly. I find it very interesting to talk too people that also have social anxiety and relate to my problems so it's far from a burden for me.
Please don't feel shy to message me if you have any further questions.
P.S. Keep in mind that English is not my native language so you might see some grammar mistakes here and there lol.
