Yes, when we have certain feelings then we should express it for sure and if we will express our true feelings then it will make us lite for sure.
And as you said, if we suppress our feelings then for sure it will going to depress us and also it will going to give stress for sure.
And here i am not giving an opinion but i am sure that we all are SLAVES of an invisible force and everyone wants to dominate each other and everybody wants to live in state of anger and fear, and not with love and peace.
And this world becoming an mess and literally and there is no word remained as Neighbourhood, no matter how much we support our neighbours they will attack us time to time and these kind of acts showcase that we are slowly becoming inhuman.
Wishing you an great day and stay blessed.
