Sometimes they take out all their stress on you,, by yelling or making you feel bad.. etc..

I do that all the time, sometimes I think I’m a mistake to them, but I know they love me.. just harsh love- one time I broke down in front of them and they said they loved me- sometimes I think they are lying but,, they are more stressed than we are. Bills they have to pay, work they have to go to.. Feeding a family...Driving us places.. Buying things to make us happy,, That’s how they show their love.

and accidentally breaking my mom and seeing the cheerfulness leave my parents

yes

Depression attack of some sort?...
