Cheating/hiding

I got married 15days back and the issue is my husband is having some skin disease and they didn't informed us about this issue before marriage. After marriage the very next day i saw and i am shocked there is very heavy pigmentation and allergy all over the body. I have consulted many doctors and they said me that there is no permanent cure for this he need to use medicine forever and im unable to adjust with him and cant even talk to him by seeing these. When I ask them about this they are telling me that it is not a big issue will get sorted in some time. My intention is when i dont have any problem in me then why should i adjust with him and in this issue my parents are not supporting me and asking me to get commit with him which i cant do. I am not even interested in talking to him and everyone is forcing me to stay with him. I am unable to take a decision on this please suggest me how to proceed further on this. Mainly my problem is im not ready to accept my life like this and no one is understanding what im feeling. Kindly do needful and help me to get out of this situation
