I made an extra appointment (for only the second time ever) last week, as I just felt 'off' - confused about the 'process' and what we were doing, and I started to build a load of stuff up in my head... Just really negative, disconnected.. I felt like I needed my T to 'fix' it and get me out of that headspace, otherwise I'd have had a really rough weekend. I couldn't pinpoint exactly what was wrong and I wasn't exactly in 'crisis' or anything.. Like you I wondered if I could justify the extra appointment, and thought I should have some big specific reason - but my T demanded no such explanation. Just be honest and tell your T what you've wrote here, I'm sure she'll understand. Don't feel stupid, I think it's better to try and do something positive instead of staying quiet and struggling along.
