I have two medical things going on at the moment. I need an operation fairly urgently, and I've talked about that, and my fears around it with my friends. They have been supportive and kind.
I'm also about to embark on EMDR for PTSD, but I haven't told a soul beyond DH. I'm afraid they will think worse of me for having a major mental illness.
Just the run up to treatment has had a huge impact on me. I'm much less efficient than usual. I keep forgetting things and getting muddled about arrangements, and I need lots of quiet time alone to stabilise myself. So I have the choice between looking distant and flaky, or admitting that I'm "not right in the head".
I live in a traditional rural community, where I fear judgement is likely to outweigh support, and where people have long memories.
So. YABU = you should take a risk and be honest
YANBU = much more sensible to keep quiet about this
