Miss_C, as we've discussed before, you have so much happening and I think it (stress and anxiety) will manifest itself in various ways. In any event, even Mr Cool here had some pretty significant panics and flip outs near the end of our first FET TWW. All the stress and worry that we bury starts overflowing at some point, like shaking a can of Coke. Plus you have the added burden of hormonal changes arising from treatment.

Try and go with it and ride it out. Don't put pressure on yourself to be perfect, and take time out to just be you (which I know you are currently doing and I am pleased). Make sure you communicate with DH even if you feel you are being a dragon because he shouldn't be isolated. Tell him how you feel and why, even if it's not making sense to you. And even see a counsellor if you think it would help to pour it all out. When we're talking next I will add a couple of other suggestions too. Take care.
