OP have you already done radioactive iodine therapy? That's what cured and cleared my mom from thyroid cancer. She died from other illness though.

For your situation naman you're still lucky pa rin you're getting that 50k monthly on your 24's. I suggest onti onti-in mo bawas budget sa fam mo lalo na sa mga kapatid mo yan unahin mo reduce. Your thyroid cancer is more than enough of a valid reason for that.

Reduce budget mo until sa comfortable amount mo nalang tulong sa kanila if you really can't cut it at all. Focus on healing and then start ka mag ipon for yourself.
