I don't think we are actually capable of seeing the love and attention that is being given to us when we are in the mindset of lack. Or the mindset of fear, doubt or low self confidence. How can you grow with someone if you're living in the fear of not being good enough? How can you give anything to your relationship or job if you don't think you are good enough? It's like a self sabotage. If you already have something, then you must be good enough to have it. It's that sick mental state that turns the hamster wheels of doubt and fear which might lead you to lose the thing you have. Seeing everything through that lens means the actions you take are based on doubt and fear. Over time, you have built your life to reflect the beliefs you have through your thoughts and actions. This is how mind creates reality.
If you weren't worthy to be here, then you wouldn't exist. You exist, therefore you are worthy of anything that existence has to offer.
Back to judging yourself. Who exactly are you to judge yourself as being good enough? Do you have an infinite knowledge and understanding by which to compare yourself to the rest of the world? Are there multiple "you's" running around with healthier bodies, and smarter minds, and happier relationships, and more fulfilling jobs? No. Then you can't compare yourself to others because they are not you. You do not know what other people's lives are like. You do not know what their experience of reality is. You are the absolute ONLY you that there will ever, ever be in this entire universe and any other universe. You are sooooo incredibly special.
You are a different you every single second just by the thoughts you are thinking and the actions you are taking on those thoughts. You are not the you you were yesterday. You are not the you you were when you woke up this morning. The power lies within you now. Decide how you are going to view yourself. Decide how you are going to live your life. If you want to be beautiful you need to start seeing the beauty you already have. If you want to be happy, let go of the mental garbage of beliefs that are making you unhappy. When you start to think negatively...STOP, and ask yourself who is saying this to me? Why am I deciding to believe this? If I decided to believe the opposite thought, would that be so bad? What if I just gave that person a break and saw the situation through a different lens.
If you think you know what someone else really thinks about you...think again. You are perceiving your version of them! You cannot understand them, to understand them, you would have to be them. You are experiencing them through your own perspective. So if you think you are not good enough, everything this person does will make you feel taken for granted, unappreciated, unloved, ugly, stupid, etc., but see those are your thoughts. You are choosing to think them. The hamster wheels are turning furiously!
Compassion. We are all human and none of us are perfect except for that the fact that we are perfect in our imperfections. You have to love yourself. You have to love yourself before you can love anyone else. It's a hard thing to do and I am struggling with it myself, but just take a moment to remember these words and think outside of the situation. And give yourself a hug because you reeeeally need one. : )
