I am losing all of my hair

I am losing so much hair and I’m devastated. I’ve been growing my hair out for a couple of years, and I was finally so happy with the state of my hair. I’ve always had thin hair, but I had lots of it. For some reason, a couple of months ago my hair just started falling out in clumps. The pictures attached here are only 4 months apart. I’ve tried SO much to stop it, from minoxidil to changing shampoos, hair oiling, vitamins, you name it. I’ve had a doctors appointment, but it was just disregarded as stress hairloss. It could be stress, but I’m a stressful person in general and I haven’t experienced something like this ever before, so I’m not 100% convinced.

Because it obviously looks like shite I did a big chop, hoping that it would at least look somewhat decent. Because I have so little hair left, buns and claw clips hurt my head almost immediately because they’re grasping on basically 5 hairs. This forces me to have my hair loose in this ugly horrible condition.

I can barely look at myself in the mirror, and I dread going out the house so much each day. Is there anyone with some advice on what to do with this situation? Is there any damage-free hairstyle that I can try to make it look somewhat ok? Or advice on what I can do to grow my hair back? Pls help me
