I could not cope. First I freaked out, and then I continued to freak out. I tried to go back to sleep, but sleep was not forthcoming.
I was still freaking out when I got back from the plasma place around ten or so. Another nap, and work, and even after a really excellent day at work, I could still feel the potential for immediate tears underlying my feeling of general well-being.
Required for sanity: a full-body snuggle session (in person or virtual) with a bondmate, and a conversation with same, preferably with some being-held while I go "Argh" about all the little things that shouldn't matter but do.
