Does yogurt kill Candida?

Does eating yogurt on a daily basis kill Candida? My anxiety has gotten so bad I can't take supplements/medication so I can't take a probiotic. I've found a yogurt that is relatively low in sugar, Dannon Light and Fit. I know you should eat plain yogurt but I've found that plain yogurt has more Sugar than the Dannon Light and Fit. Does this work against Candida?

Also I've read that people with weakened immune systems shouldn't take Streptococcus thermophilus because it can make you sick. I thought if you have Candida, you have a weakened immune system. And I also have Hashimoto's as well. Is this strain of bacteria safe for me to have? It's found in practically all the store bought yogurts.
