Verb conjugation of "officiate" in English

Regarding the meeting in early May: I could not reschedule the appointment at my daughter's doctor and I will definitely know if I can come during the first 2 weeks. I guess we should talk next week.
I usually do not travel, and if I do, then only to England, when I visit my parents who live in a suburb of London. I can not afford to travel too much, because it is a very large expense.
Many thanks for your suggestions. They are very useful. I can't answer your mail now, but I will come back to you later when I'll have more time. I hope that you and your family are well!
