Name changed for this as was worried 
I’m just a mean person, when I see my friends who have just got promotions, deep down inside I’m jealous, I wish they hadn’t as I haven’t got one and I work quite hard! When my SIL and her husband bought a house in France and moved there to escape Brexit, instead of being happy for them, I hated them and I hated how DH and I couldn’t do that. When my DSIS DD got into a lovely Oxford College, I was pissed off how my DD1 got rejected. When DSD did better at Gcses than my DD and has a perfect boyfriend, is very pretty etc I felt angry that DD doesn’t have that and hates herself for it.
I know my thoughts are stupid and childish and mean. I know. But I can’t help it, I genuinely can’t help being a shitty person.
AIBU to ask how I can change the way I feel about events and have a more positive outlook on life?
