ppd with colic baby

You guys, today has been so rough. I'm currently taking Zoloft but my insurance ran out and I currently can't get a refill on my medication because I can't afford it, which I'm scared because it's helped me so much! But anyway my baby has cried all day. I went to target to get him some gripe water and also got this lotion with lavender to help him calm down and nothing has worked. I've tried everything!!!! I'm exhausted, I feel like running away from my family and I know that sounds terrible but I feel like I need professional help. I feel like im going to go insane.
