Who do u vent to ?

Is it okay to vent to random people on social media ?
There's this girl on twitter whom I talk to often & I really want to be friends with her but she ignores me when I say "I wanna know more abt, tell me what's going on " she only focuses on me but I feel like its uncomfortable ...I follow psychiatrist on insta & they say venting to someone who goes through the same issues creates a trauma bond & u should do that with a therapist ...I don't really wanna hurt anybody but...just talk cause I have no friends irl nor on social media I'm really trying ..loneliness is hard & idk how to love/appreciate myself & be there for myself when I'm having bad days ..facing problems is super scary
