Being the true you is really the only way to be healthy and happy.
We know this to be true, don't we? If we can be ourselves at home, it is the best place to be. We re-energize ourselves at home when we can just "be." But if we feel criticized or guarded around our family or others we live with, we don't feel comfortable or happy in our homes. Isn't this true?
Being the true you means just being you despite what others think, say, or expect of you. How they respond reflects on them. It is their issue, not yours. Of course it's not okay to be rude to them; but I think we care too much about what others think about us and our choices. It's our job to be ourselves and allow others to be the same. It is not okay for either party to take all the power in the relationship. It should be 50/50. Don't allow others to manipulate you or control you in a relationship. As children, we didn't have a choice about who was in control, but as adults we do.
It is our job and our right to decide who we want to be. Come up with your own ideas, rather than what you think others will like, even society. Who are you? What do you truly enjoy? Many people think "society" knows what's best. be it where we should live, what kind of house we should live in, what kind of counter tops we should have, etc. We think society knows what beauty is, what a good career is, what activities we should be doing. How is that even possible if everyone is unique? We all have different needs and wants. We are individuals.
When we are not our true selves, it causes tension in our bodies. We become afraid that we won't measure up to others. How can we remain relaxed in our bodies when our thoughts are filled with fear? When we are true, we relax into ourselves.
Action
You may at first feel nervous when trying to be the true you. Will others like you? Will they be mad at you for not being who they want you to be? Even if they are mad, they will get over it. They may like you even better because you'll be more relaxed and happy.
Sometimes I hear a person who has been married a long time say, "my spouse is not the same person I fell in love with." It is possible that they were their true self at first and then became the person they thought was expected of them in being married and being a parent. Sometimes the person changes in response to our trying to change them to be more like what we want. It's not their true self, nor is it fair to ask them to change. You may be happier to let them be their true self again.
Give yourself permission to be yourself and give others the same permission. Life will be so much more fun!
