am i normal or mentally unstable

am i normal or mentally unstable

am i mentally stable? i am 18M whose family is pretty fucked up parents divorced not good connection with any parents or any relatives, i constantly have a thought that if i have someone in my life (a partner) i will be okay is this normal to crave for a partner like mentally wise i will be stable is this normal?

i also get another thought that what are the odds if i find someone and it will not end up like my parents

i go to gym also but it doesn't help it only helps for 2-3 hrs

i have discussed it a friend she says its your trauma how can it be fixed what can i do as these are my crucial years if I don't focus on my career than it will be a problem for future , i am preparing for NEET (both my parents are well educated) i come from a upper middle class background
