Should i tell them?

I was sa by deaf brother when i was a child around 6yrs old.I had forgotten but got my memory back when i was 10 but i tried to forget it.Eventually i started getting triggers when i was around him.We live in same house so like everytime.I was already shy introvert and sensitive so my family who grew up poor in struggle always had pressured me in school.I got depressed anxiety plus being called useless by family comparing with other kids didn't helped. Tbh i cried more cause of what they said than knowing my traumatic memory.I always tried to forget everything that they told me to do daily stuff.I had forgetful habit so just had to put up a normal mask. But when i reached college daily stuff became hard like i couldn't even study as i used to.All my energy felt drained i felt tired my grade dropped i couldn't concentrate.Later i became unemployed so even more bla bla from everyone.I failed at everything and sometime when they used to praise him that he atleast have a job i felt not so good:(

I have forgiven him cause i think that he didn't knew what was right or wrong as he is disable cant hear cant speak and his brain was slow.Tbh he acted normal the whole time.He's even married with deaf girl has a child and he is really responsible and worried about his child's future as a deaf family with low income. As i've seen him i know that he has changed to a better person.And the family loves him and if i tell them the truth everything will fall apart.I know my family is still a good person who has struggled a lot so i wanted them to live in their own bubble of life away from the truth. Plus i was raised by single mother and my mother's family only.

I'm 26 now and my life is mess.I have no motivation neither ambition.I had depression anxiety the whole life.I finally got a job as cleaner in abroad but exploitation was max so i applied for another country for better opportunities but ended up not finding any next work so i have to return back to my family in home country which i don't want to.I would rather delete than go back living the hell which i know with them talking even more shit about me.And they're already telling me to find any kind of job somewhere in other countries .The reason i couldn't find next job with good opportunities is because i couldn't study language. No matter how much i try to study my brain refuses to take it inside. Not just my mind now but my whole body just screams to let it rest.

I know if i had a different personality then maybe the later story would have been different too.Probably cause my brain realized that there's no escape now to survive that it's trying to convince me to tell them the truth to not get blamed for being a failure.
