Observing your thoughts, feelings & sensations is the grist of the practice.
While meditating we are simply seeing what the mind has been doing all along.
The practice of lovingkindness can uplift us & relieve sorrow & unhappiness.
That's why it's called a practice. We have to practice a practice if it is to be of value.
No one looks or feels attractive when angry.
Support the type of thinking that leads you to feeling good, peaceful & happy.
