Sometimes I think my ego is overdonexcessive, sometimes I think I am a fool without ego.

"overdone" doesn't quite fit here, I'm not sure if this is exactly what you mean but it sounds better. "overdone" is more for, like, objects that somebody has *worked* on. Difficult to explain exactly.

I was broseught up like a sheep.

I don't think we ever use "rise" in this sense, like a child growing.

My parents caresd about little about, as long as I did well in my studyies.

My mother would ask me to do many housework, but I was always too lazy.

"housework" is uncountable, so we can't use "many" (but you could say something like "many housework jobs"). Normally I'd change it to "much" or "a lot" but for some reason they sound weird or don't seem to express what I think you want to say.

I think the best fit is probably "My mother would often/frequently ask me to do housework". Or you could just say "many chores".

When I was a primary school student, I sleldom went outside with my peers.

So many neighbors or my parents' friends praised me ofas quiet.

Or "praised my quietness".

I never tellold them the truth was that I thought most of my peers were so tedious, I would rather stay alone than playing with them unhappily.

Or "I would never tell them" - "Expression of habitual aspect in past time, as in 'Back then, I would eat early and would walk to school.'"

Most of the time, I live without any goal, like a sheep.

I never have strong motivation to do someanything, even though I thought I did have.

Maybe "even if I thought I did" would more closely match what you want.

"did have" is okay, just sounds a bit awkward when "did" is sufficient.
