These are more than likely to be either blocked sebaceous glands or blocked hair follicles.
With squeezing, you may have caused an infection to spread, hence now having 3. They will hurt if you try to pop them.
If you are able to make your own appointment to see your doctor and get to see him on your own, then do so. Sometimes, these do shrink on their own, but sometimes an antibiotic is prescribed to stop the infection spreading further. The reason you are not able to pop them is that there is not head formed yet. Sometimes these cysts do not form a head, but can still fester and an infection can spread inwards.
I am sure your mum has also experienced something like that at some point in her life. If you need your mum to take you to the doctor, then do tell her. Try not to squeeze any more, this just spreads the infection.
