Mosquito Bites of 3 months got extremely worse, any ideas?

Definitely don’t sound like mosquito bites, particularly because the bumps appeared in July.
Sound like boils to me.
Where are they located? Depending on that, it could be a couple different things.
How are you feeling in general? If the lumps seem infected (i.e. you’re running a fever, feeling ill) you definitely want to see a doctor. Check for free clinics in your area, or just go see one and work out the details of “no insurance” later. Every clinic and hospital has options for people who can’t afford care.
If they are leaking pus, DON’T block it. Try and get it out. Just do it as safely as possible in case it’s something that can spread (boils usually don’t, though). Wash your hands and the area well before and after.
Put an antibiotic ointment and a bandage over them afterward.
If they aren’t infected already, draining them will help prevent that from becoming the case.

Draining them is much like popping a pimple. Be gentle and squeeze out what you can. Stop when it’s only blood coming out, wash and cover them.
You can also try making a paste with epsom salt and water and putting it on the lumps and covering them with gauze or a large bandage to help draw out what’s inside.
