First of all remember that you can’t change the toxic parents fully. The chances of success in such an attempt is very less. Approach this issue with a sense of reality and do not foster unnecessary expectation.
The toxic parents always raise their tone and justify it by saying that the ward’s emotions are unimportant. But the emotions of any individual cannot be belittled. Believe in your own feelings. It will save you from deep sorrows.
Mind the limit of everything
The parents’ unnecessary interference may sometimes cross the limit. It will have far reaching consequences.
When parents don’t give you the required support and consideration find out an alternative support system. You deserve the support of somebody who can understand your feelings. However finding out such a system is to be done with utmost care or else it may lead you to more and more troubles.
