Im at a loss with teething

So our baby has had hot red checks that come and go since she was basically 9 weeks old. She’s seven months now and not one single tooth. Despite the constant red checks, grumpy baby, constantly dribbling, always covered in dribble rash despite me changing her outfit and bibs multiple times a day, it never ends. Endless calpol, teething granules, screaming out in the night. Refusing bottles, then being hungry. Sticking her tongue out or moving it around her mouth. I literally have strangers stop in the street to comment on her. If I hear “awww is she teething?” One more time I may burst out crying. I know this seems over the top but it’s effecting my mental health. I never ever have a happy baby and it all points to the teeth and I’m just so sad for her. I’m even questioning if it is even teething or is it just her and this is how she is. But I don’t know. I’ve not slept for months. I’m so worried it’s also effecting bad habits in her as she is constantly stuck to me because she needs 24/7 comfort from me which of course I’d do all day because I love her more than anything and I just want to see her happy. But to have nothing ever come of it, I’m getting really touched out and I now can’t go anywhere without her crying out for me. Sorry this is such a negative post I just have nobody to talk to. My mum, MIL, friends and sisters just say oh well this is teething for you, but when I ask if they had MONTHS of it they say no a few or so here and there. So they just don’t get it. My sister said she didn’t even know her daughter was teething and the teeth just appeared which is why it’s got me wondering if there is something else. It’s not a tummy,gas,reflux or food related issue I know that for sure. We’ve also been there and got the T-shirt and thankfully sorted that issue out. This is something different
