Sulfamethoxazole and job

My doctor prescribed me this medication (3 days/2x a day) to treat a minor UTI. It did its job but now i have a horribly itchy rash on my feet and lower calves. Furthermore, I was already struggling with an eating disorder before I started this medication, and now it is way worse. It completely took away any appetite i had before

I was prescribed Sulfameth for an abscess on my inner thigh. I have been on it for two days now and the side effects are getting worse with every pill I take. I have felt racey, which has led to the restless sleep; I have had no appetite, no energy, shakes, panic attacks, depression, & mood swings. I definitely do not feel like myself. I feel seperated from the world, or like I'm walking outside of my body. I am running a slight fever every now and again too. There has to be something better out there that can do the same job but with fewer or less severe side effects!!!!
