Greetings friend @josevas217, certainly money does not buy happiness but it does give the emotional tranquility that the person requires for peace of mind, personally both cases that you mention in your questions have happened to me, I comment.

At the beginning of last year in the month of March I was able to get a job that allowed me for 6 months to have that economic stability that I had never had, I did not worry about the food in my home and that was enough to be emotionally calm, but for reasons beyond our vonluntad all workers were fired for family problems of the owners of the company, when that happened the following months began to arrive debts and with it the worries and emotional instability again.

Friend certainly when one has an economic stability automatically you have your emotions to the maximum because unfortunately in our country everything is money.
