I have mixed feelings on this topic. When I first started to post here on this board I posted over in the MS forum. I was having many difficulties with my physical symptoms of that but also with my depression and my new autonomic disorder was going all-haywire. It made for quite the combination. Needless to say my mom whom I live with currently, found out that I was posting here and being concerned for me and what I was going through as I wasn’t talking to her, made herself an account and logged on to see what I was posting and saying. She did this a few times and once she saw for herself that I was talking to people and it wasn’t something negative she stopped coming on. However, her doing this did greatly bother me as I felt that she invaded my privacy in a way. I didn’t invite her to see what I was writing on here. I spoke with her about it and told her how I felt. Once that was done, I was okay with her coming on and seeing whatever she wants too. I think it was the whole going behind my back thing that got to me.
I do believe that for everyone who posts here it is up to you and your preference. If you have someone close that knows you post here and you fear that they will log on and read what you have written than maybe you need to ask them not to do so. Posting here can be as personal as writing in a journal except you have others that write back to you. IMO...
