that is scary about the light???!!!! I'm glad you were able to go to another place where you feel safe.
I would NOT cancel in order to meet with H. You have an excellent reason not to. Don't miss out on something that is precious to you.
I would not include any explanation of why you aren't available. First you don't need to give an excuse; Second it is more mysterious.
I would just write,
'Hiya, sorry I didn't reply yesterday my phone ran out of battery. I am free most of the weekend and Monday and Wednesday night. Do any of those suit? Let me know which you can make. I dont feel comfortable signing the form until we've had chance to discuss the implications.
Thanks J
If you feel the need to "cushion" it say something about the cat or what you did today but you don't need to give him any excuses or details about your plans. If you don't feel the need to cushion it either that is OK too, because he is pushing you to take care of "business", you can respond in a very businesslike way. It might even be a good 180.
