I just wanted to say that I know what you're going through. When I was younger, I felt the pressures of society telling me I needed to have friends, be social, be part of society etc...I was always scared out of my mind in a group setting and had to escape with alcohol to feel slightly comfortable. I always felt awkward and embarrassed about anything I said. I suppose I kind of gave up at one point in my 30's. Though I didn't hide in a room, I hid in my home. I did what I had to do to pay the bills, stock my fridge and take care of my pets, but otherwise, decided I wanted nothing more to do with people. Human interaction is fine for me if it's anonymous and safe, like on this forum, but otherwise, humanity has let me down too much and I prefer to be alone. I do have a bf but that isn't lasting and I will ultimately be a single hermit woman again by next summer. I have pets to care for, that's all I need. I'm not promoting the hermit life because it's not for everyone, but I feel like most people think they NEED society for happiness and fulfillment. I was given advice for years to be more social, to get out more etc...but it wasn't what helped me. I love my private, quite life of solitude and I don't feel there is any need to change that for the sake of norms. Besides the problems I'm currently going through, overall, I've filled my life with hobbies, interests and nature and I don't need much more.
On the other hand if you need friends, family, relationships and society to feel fulfilled, then don't listen to me!
