Somethings QL has taught me in the last few days:
1)Don't take to heart too much anything anyone has to say for or against you.
2)Don't be afraid or ashamed to speak the truth and/or voice out your opinion.
3)Be most patient and forbearing with everyone, regardless of how they are to you. As per our faith, always repel evil with good, and be the better person.
4)If you find the opinion you held to be wrong, don't be ashamed to admit your mistakes, regardless of how arrogant and obstinate be anyone else.
5)Not always will we get the kind of response we hoped for. In fact sometimes what we face will be disheartening too. Be patient still, God is after all with the patient.

These have all been based on my personal experiences and observations here, which I wished to share. Perhaps it may help you and others as well.
And hope your mom is doing well now. My salaams to her and all your loved ones.
