I am about to leave year 11 and have had some difficulties with mental health and other things, i had a teacher from year 8 to year 10 and she left about a year ago and still miss her and would like to catch up with her but the only contact i have is her facebook, i wouldn’t be requesting her or anything but would it be weird to just message and ask if she wants to have a catch up with me? We had a very close relationship.
