Answer
First of all Eman, I am not a vet. My profile clearly states I am a Registered Veterinary Technician. I cannot diagnose anything.
But from what you are describing I can tell you it sounds like your cat has lymphoma. That is not uncommon in areas where cats are not routinely vaccinated for this deadly disease.
I would have to say that you should get the cat tested for this. Persistently enlarged lymph glands are the tip off, especially this wide spread.

All the other symptoms are secondary to the immune system being almost completely undermined.
Testing is the only way you will know the nature of this problem. I would have a combo test done for FELV, FIV, FIP. Lymphoma is generally a manifestation of a cat have FELV, or Feline Leukemia.

I am sorry I cannot be of more help.
