Giving birth

I am faaarrr from my due date but the scariest part of being pregnant for me is going to be giving birth this is the first time I even really worried about since there’s so much other stuff BUTTT I’m afraid. I’ve had experiences of instant painful headaches when using the bathroom which last a few secs. I a lot experience anxiety and have these episodes where If I skip too many meals constantly I get the attack, I feel weak/faint , cold sweat, nauseous. My sugar level drops 😣
