Do you often pretend to be someone else? Just to fit into the group? Or maybe, even worst, you are playing the role of a servant or even slave, just to be accepted? Is that what you are doing? Is this kind of behaviour makes you happier?
Yes, it might look like you get accepted by the group? But look closer. Are those people, really accept you? Or maybe they are just happy that there is someone who serves them? That someone is doing all the dirty work? Is this the way you like to behave and be treated? For how long you will decrease yourself value?
I want to explain to you one important concept. You are human. With all your imperfections and assets you were born with and developed till now. You have your character and personality. There is no perfect being in this world. We all have good and bad bits in us.
Moreover, human perfection lies in human imperfection. In making peace, with all your parts, that were given to you. And in working over to become a better version of yourself, working on those rough bits. You need to understand this if you want to be truly happy and in peace with yourself.
So please, do this for yourself and stop treating yourself as a worst than others. Less worthy. Look at yourself with compassion and love you deserve. With the love, as you would look at a little, innocent child.
Understand that you, whole, deserve to be respected and loved. With all your flaws and virtues. Stop focusing on the first ones too much. Work on them to become a better person. But most importantly, see yourself as equal as anyone else. As a great human being, created and gifted by God, Higher Instance, Universe, you name it.
You get that all, your defects and qualities, together with free will, to be able to decide for yourself what you want to do with them. Will you just sit and watch them? Allowing to impact your self-esteem. Or you will accept them and do something to grow and improve yourself? The choice is yours.
Be positive, be blessed, peace out.
