Never feeling good enough....

I have always had this feeling ever since I was a teenager or childhood actually. I have never felt good enough to be loved or in sports...just in general. I know somewhat of what it stems from but that's besides the point and it can't be changed now. So my big question is how do you move on from these feelings. I do my best to be encouraging and uplifting everyday, it doesn't always work but I give it a try everyday. It's always so easy for me to uplift others or lend a helping hand, in fact I love doing that!! I would rather sit and listen and give advice or help a friend then to tell myself one good qaulity I see in myself. I constanly feel like I am not good enough and struggle to find that self worth...why I don't know. I really wish it wasn't this hard, I see the confidence and radiant beauty in others and I always think to myself why can't I have that. Is this a normal woman thing or am I really just too hard on myself? I just really want to know are there others out there that feel the same way? Sometimes I think that if we all opened up a little bit more than it would lighten the load off of others. Alot of our problems are started cause we feel alone and that no one else struggles with what we are going through. So if there is anyone out there that feels the same way I would like to know and maybe we can come up with encouraging words to help on a daily basis. :) Just random thoughts and feelings that usually run through my mind on a daily basis but I never act on it, I just always push it aside and move on.
