Feeling unworthy

I am struggling to fit in at work, I am always feeling like I am not good enough and I am tired of feeling this way but I don't know how to change. At work and in my relationships i act stupid, and i let people push me around because i don't think i am good enough. What do I do to change, I don't want to keep going this way. I grew up being told that I was not good enough, and that I would never be anything and that's what I have come to believe. My whole life I have been living up to other people's expectations of me for approval and acceptance. I really want to change, and take myself out of this shell, break free and learn to fly. I know I can do it and I know I can change but I just don't know where to start. I want to discover God's power within me that enables me to reach my full potential, to know, appreciate and love my true self, be the best I can be and the person He created me to be.

It's hard, and I feel as if i don't belong to this world. There is just ernomous pressure to conform to earthly standards, and I need the strength to fight the feelings of unworthiness and learn to see myself the way God sees me. I know of His unfailing love for me and I feel and see it everyywhere i go

My daily prayer is that I may be changed by a complete renewal of my mind and heart, that I may find who I am in Christ and come to love myself.
