Overthinking

I always thought that if I was going to be good at one thing in life, it was going to be being a mother.  Somehow, all of my shortcomings everywhere else was going to be made up with how great I was pregnant and as a mother.  It was all going to come to me so naturally.  Well, I'm starting to doubt all of that.  Just another thing that infertility is robbing me of.  I see new mothers and think, "they are so much better at this than I probably would".  I mean, I can't even get pregnant.  I know, I know, chin up.  What if I was the worst pregnant woman?  What if my hormones rage out of control and no one can stand to be around me?  Or what if I have a baby and am not able to handle it?  What if it's all too much?  After all the ups and downs the past two years of ttc, I don't know how good I am at handling much.  Could I have a baby, a full time job, and a house to keep up?  I don't know anymore.   I have had too much time to over think all of this.
