Ouch. Your mum and her partner are deliberately doing that? It's no surprising you are annoyed. Suppressing your annoyance is not a good thing, but causing trouble is usually not worth it. I applaud you for keeping it together, at least your mum has came around to calling you max, that's a start. As for getting somewhere, that's fantastic news! Yeah, these three months will be a drag 😛 But you'll look back and most likely think, 'actually, it fly past'. Do things to keep your mind occupied, the time will flow.
