I think I know how you're feeling about talking about it. I noticed I kind of withdrew socially a few weeks before the op, that means, there were maybe three friends who knew about it, and I didn't talk to or see anyone but them. One was a guy I was dating, and he bailed out of the relationship when I came home from the hospital.
For the next weeks after OP, I still only saw those two friends, and had a very hard time leaving the apartment. Just to go grocery shopping and make sure I was moving around enough every day. It just felt too weird to be on the street, and forget about buses or the subway. Part of that was my feeling physically sensitive and vulnerable. But part of it was also this deep feeling that I had been surgically changed into a a mutant species and wasn't quite really human any more, because of the stoma and the bag, and that my systems would never again function like a "normal" person's system.
Then I was in a rehab clinic for 3 weeks. I hated it there. I didn't want the other patients asking me any questions, didn't want to talk to them at all. I couldn't stand it that I had to sit at a table with people I didn't know and eat with them three times a day. I started taking meals up to my room.
These feelings have normalized in the last week or so. I've even gone into stores and tried on clothes. No one notices that I have the bag. I've realized that it really is true that no one can see it, no one would even ever suspect. I can go through the day and start to think about other things. I am starting a new job day after tomorrow, and I know it means I will not even get a chance to think about the bag and stoma for at least 8 hours, except when I know I have to empty the bag, just like everyone else at work will have to go to the bathroom.
That's what I mean when I wrote, give your feelings a chance to heal too.
But it really helps if you have at least one friend you can talk to, who understands that you need to talk about IT.
I have my oldest friend, far away, and we talk on skype. She is being wonderful to me. I even showed her the different kinds of bags (on webcam) and we talked about the pros and cons. This did me so much good, just to have someone I can talk about this stuff with in a totally normal way. That's the most important thing, getting it all so that it is just normal, I think it takes a few more weeks for you and I really hope you have a friend like that. It could even be someone you didn't expect. At some point in the near future, I really think you will start to feel like you want to be around people socializing the same way you always did.
