Feeling like a Horrible Mom

Just needed a place to vent- Lately my 2 month old baby has hit a rough patch- not sure if it’s colic but it just seems like she’s always crying… she hates tummy time and has a bit of a flat head and maybe torticollis. I cannot put her on her stomach without her screaming the entire time. I also have a really crappy milk supply, I’ve tried everything so she is pretty much a formula fed baby which I feel ashamed about. My husband works all day so it’s just me and her the majority of the day. I’ve had a UTI since I left the hospital which is painful and just adds to everything. I’m so exhausted, overwhelmed, overstimulated, and just feel like my own baby hates me. When she cries and I hold her seeing her tears just break me and I feel so crappy depressed and empty inside. The guilt of feeling this way is eating me up too because obviously I love my baby girl more than anything in the world, and I’m so blessed to have her, so I feel guilty even being exhausted. Anyways, if you read all this any advice would be appreciated ❤️‍🩹
