Inputs from mothers please...

I know this is a sensitive topic but as an adult child and chatting with friends, I have found this to be a common phenomenon. Any thoughts would be appreciated to relieve this pain.

Mothers seem to be (and are) destroying their children's life on purpose. First subconsciously then as years go by, they would do it on purpose.

For example, they would frown upon the children's success by saying things like... so what if you are gettting good mark at school... so what if you are earning a living yourself... And they have actions to go along with their words such as making noise when you study or phoneing your workplace to disturb you.

Thoughts please.
