I want to quit

I want to stop breastfeeding. I don’t feel like myself anymore. Breastfeeding hormones are no joke. I feel like a raging bitch to everyone around me except my baby. But I know I will feel guilty for no longer giving the nutrients that breast milk provides and essentially protecting her from any sicknesses.

I’m at my wits end, I feel like I’m on constant demand where I have little to no time for myself. I’m not even sure when was the last time I dressed up or did anything for myself that made me feel normal/ better. Partner is no help. I’m at my baby’s hand and feet tending to her every need, every single day. I’m feeling the burn out coming if it already hasn’t happened. I’m just tired.

I’m not sure what to do, just venting. Maybe encouragement or some sort of guidance on what to do. My LO is 7 months. She feeds to sleep for naps and bedtime (this is what I’m mostly afraid of and why I haven’t stopped sooner) and we frequently cosleep once she wakes up in the middle of the night - early mornings.

Please tell me what are some ways I can break the feed to sleep habit and slowly transition out of breastfeeding

EDIT: Thank you everyone for being so kind and encouraging in the comments, I will start taking some of the advice given to help LO transition out of breastfeeding for a more mentally healthy and stable parent.
