Does everyone have toxic family or am I only one?

Surrounded by people who are so envious or not well wishers.

My brother's wife is jealous coz my husband took me on trips and always compares my bro to my husband ( even though they are way better settled than us overall). My husband's sister seems to brainwash my MIL against my husband since my MIL has repeatedly admitted in front of her that she feels more for my husband than for her ( for whatever reason).

Cousin congratulates my mom but not me (when I had my daughter) etc etc

Why are people so complicated?
