Just got a positive test and im scared

Three days ago the GI doctor called me and said my stool test came back positive for C.diff, she wanted to make sure it was a active infection and sure enough after extra testing it came back that it was in fact active.

I pushed for a stool test because for the past 2 months ive had debilitating nausea, ive had a upper scope done, countless blood work and they couldn't find anything, they didnt want to do a stool test because I haven't had diharrhea at all but I pushed for it and now here we are. My only symptoms are debilitating nausea, literally 0 appetite, terrible stomach cramps, fatigue, constipation and strange bowel movements. (We are starting to think that my anti nausea medication maybe is masking the diharrhea)

My doctor put me on Vancomycin 125MG 4 times a day and gosh it has made me feel even worse. My nausea has amplified, I cant eat at all without wanting to barf and im so tired I cant get out of bed. I talked with my GI doctor and they told me to just push through this, that I need this medication to feel better but I can no longer see the light at the end of the tunnel. If anyone has any positive stories or anything to make this feel less grim please share cause im worried I'll never get my normal life back :(
