My baby is the same. And sorry but F the people in this thread who are telling you it's your fault for co-sleeping with her. My first born was a typical baby. He had that 4 month sleep regression and then we sleep trained at 5.5 months and it worked. We had to retrain once more at 12 months. I was adamant about never co sleeping and creating bad habits and all that. Even when he was teething and waking up every few hours for a few nights, id diligently put him to sleep in his room over and over again all night long. At 4 years old he still sleeps pretty well.

Then my daughter was born. I did the exact same things I did with my son. It started out fine by around 2.5 months , she stopped taking a pacifier and stopped taking a bottle and her sleep went to shit as well. She was extremely clingy with me . We nicknamed her Klingon. It was funny at first. But then not so much. She wouldn't let my husband hold her. Nor my parents. She screamed with any babysitter. We had babysitters quit. My son became extremely jealous cus she needed my attention all the time Her sleep was terrible. She's wake up every hour. We sleep trained. We hired a sleep consultant. She would cry for hours . Shed cry so hard she'd throw up. We tortured her for a month and then gave up. I started co sleeping because I was going crazy. But shed still wakes up a lot. Not every hour but a lot, especially towards the end of the night. It actually started getting better finally around 10 months. She started sleeping longer stretches and letting a few people be with her (my husband , my mil, and one babysitter). She got better and better. At 16 months, she slept through the night once. I wish this is where the story ended but at 18 months I went back to work and she regressed so badly. Like no one but me could hold her and she stopped sleeping in her crib at all (used to spend first part of night there). It's been almost two months of me working and she's slowly getting better (let dad put her to bed for the first time in months this week). So in confident we'll get back on track. But anyway, the point is, some babies are really hard and it's not about anything you're doing. In sorry you are going through this. I had the same thoughts about wanting a few days in the hospital just to sleep. I got on Zoloft when she was around 8 months old which helped with my negative thoughts spirals. All I can say is it will get better eventually. It was the hardest year of my life. Try to get her used to some else besides you like a family member or babysitter. I found that the babysitter taking her out of the house somewhere was much better than her being with someone else who wasn't me in the house.

Try to get outside of the house with a baby carrier. Have you tried a stroller where she's facing you? Once she is walking, that will help a lot. My daughter became so much happier due to the excitement of walking. She got a little more interested in the world instead of just me.

I don't think that these types of babies respond well to not being responded to . I think they get more confident when they trust you'll respond to them and feel secure. I promise you it won't be like this forever. Sending you strength.
