I think that people post the age of 18 are responsible for themselves and for their acts. I don’t agree with theories of blaming others and especially parents – once someone is mature he is responsible for himself and whenever deals with an issue, he must resolve it on his own.

This is absolutely right. We just have to identify that our upbringing influences the type of adults we become, and with this realization, work on making ourselves better adults. What our parents did or didn't do is in the past, and what matters is fixing ourselves and forging a future where our kids do not have to suffer the unpleasant experiences in our upbringing. I'm sorry to hear about your case. You sound like a strong person and emotionally intelligent person.
