Postpartum anxiety

So ive had problems with anxiety since i was in middle school(21 now) I was on medication for about 6 months in 2021 and it was not a fun experience. I was off of them for about 3months before I got pregnant and now at 7weeks postpartum im way worse than ive ever been. I cant sleep half of the time, im constantly worried/thinking something will happen to my baby, i have a short fuse, and I dont trust anyone other than my husband with her- she cant be out of my sight with anyone but him. I know I need to say something but I dont want to go back to the same meds, or have to try new stuff while having to care for my baby. Im exclusively breastfeeding (we have bottle fed a bit, but after baby going through a growth spurt i have used my entire supply i had stored) so i cant have a break- but i cant really do that either without losing it bc i want my baby. If I say something to the doctor they are just going to put me on meds right? Like i dont even want to say anything for that reason, but i know i need help.
