i had 2 c/s, and honestly?? if your worry is about anxiety, i would probably go with a vaginal birth. i suffer anxiety too, i'm medicated for it, so i'm not just sprouting crap.
c/s can make you feel extremely vulnerable, you are numb, on a bed, with everything going on around you. it can spark a panic attack in people who don't suffer anxiety.
c/s recovery is a lot worse than from a vaginal delivery, if someone mentions the 'soft way out', tell them to get their stomach's sliced open, swished around, and sewn back together. not nice.
a vaginal delivery, which obviously you're very anxious about should be a more empowering experience than anything. you will also use up a lot of the adrenaline that you will have pumping around your body from the anxiety, which will make your time with your baby much nicer. adrenaline is one of the main causes of anxiety, so it helps to expel it.
i also *think* that going through a vaginal birth will give you an amazing feeling of achievement, it may even help to alleviate some of your anxiety for future problems, the whole "i did this, i can do anything" mentality.
either way chickie, only you can make this decision for you, i'm just offering my 2 cents worth from personal experience xoxo
