It will only take time to adapt in maintaining a good and mental health especially for people who are living in past experience. But deep down the people who feel more depressed are people who find it difficult to share their feelings to others.
It can only get better when having the positive mind to move on and correct past mistakes. Though, we are humans and in that sense we are not perfect but to maintain a good relationship and mental health, it is advisable to seek help from other people who can assist in reducing the pressure and depressed situation.
I am not so sure. Perhaps they are unwilling to show their true feelings. That nagging in their head that they are part of the issue.
