8m Regression

I am losing my mind over here from exhaustion. Since about 3mo my baby has been able to fall asleep in the crib on her own with no crying. She took good naps and dropped her last night feed around 6mo.

For the past 3 weeks, she cries when I start to put her sleep sack on her, cries when I put her in the crib, takes ages to fall asleep even though I can tell she’s tired. She wakes up every 2-3h and takes ages to fall back asleep.

I’m trying really hard not to create new sleep associations that I’ll have to break later, but I am exhausted from sitting up all night trying to soothe her back to sleep. The second I take my hand off her back she starts howling again. I feel terrible for her and I don’t know what the best thing to do is. Should I just start trying to nurse her to sleep? Any time I’ve tried that before she wakes up as soon as she unlatched. Should I try rocking her to sleep? I’ve never had success transferring her to her bed and keeping her asleep. I can’t bedshare (I have severe anxiety and intrusive thoughts about SIDS and accidental suffocation)

I never experienced this with my first. (She’s 2.5yo, started sleeping through the night at 12wo, and I’ve literally never had to go into her room in the night since then, not once.)
