Baby waking all night , everyone night

Please help! My daughter slept through the night for the most part up until 4 months ish. She is now 7 months and she’s been waking legit every hour/two hours ALL night. I put her down usually around 7/8pm and get her up for good around 630 or 7am. She’s exclusively breastfed and having 2 solid meals a day. Breakfast and Dinner. I’ve tried lots of different things, dream feeding , putting her down earlier, later, giving her more protein in her diet/meals and tons more things. But nothing seems to change/cut down her wake times. She usually naps 2 times a day and for a total of 3/4 hours. This past week she won’t go down for her naps no matter what I do. I know feeding to sleep sometimes can be a quick fix sometimes, but I do everything and the only way she goes back to sleep is if I give her the breast for a couple minutes and she goes right back to sleep.. most times. I’m totally exhausted and over tired. The bags under my eyes are horrifying at this point. Looking for other moms that have advice/been through the same sort of thing.
