Intrusive thoughts. What if it's my fault dad left

[Against_the_current]

I was gaming before sleep and someone raged in the chat "hope ur mom dies" idk towards whom. I thought how stupid it is, moms, pets. Everyone dies but pets really fast. And i thought we got him for Sister's 11th birthday and a month later dad left. Sis is now 15. All her bdays ruined. She had homework to write about her bday.... She couldn't. I got Bob because i was bullied and i wanted an anxiety relief and bond to my Defender. And i was so stressed that i couldn't sleep alone and dad slept with Bob. Sis said Bob is like cursed. If the bullies destroyed my family, my sis bdays, my mental health. And this made me study psychology and then igot more traumatized from dad leaving consequences htat i might not be able to work it and be left broken and broke, with sis too, damaged, because i was bullied and wanted company. And my bullies don't even know, don't even know hte consequences to my family, the therapist bills, everything. They're triving. Unfair. In Korea even a bullying rumour will end their career, and here my bullies are probably sucsesful, rich and loved. They made me destroy my family and put sis through hell and watch her act weird, dress boyish
