I find that some people resist feeling any compassion or sadness for themselves, because they don’t want to fall into “self-pity” or feeling sorry for themselves.
The most important relationship you have or will ever have is with yourself.
Every day, all of us humans encounter feelings, thoughts, and behaviour- in ourselves and others- that we consider less than ideal.
Think of a toddler who is learning to walk. He falls down all the time, and that’s OK.
One thing we were all naturally good at as children, but tend to lose the ability to do to various degrees, is finding pleasure in small things, or celebrating.
We have all behaved in ways that were less than ideal, and we have all experienced the bitter taste of guilt.
When you think of all the little things you judge yourself for or worry about, and how much they actually matter compared to how important you and your well-being are, there is absolutely no comparison!
It is very common to grow up without the need for attunement to your feelings being met ie your feelings being seen and validated.
