Help

I recently bought new pants on amazon and my mom touched the package with my pants to give it to me and now I don't want to wear them because I feel like it is "contaminated". Am I overreacting? Someone please help I am going crazy with this to the point where I throw good clothes away to buy new ones because I feel like it is "contaminated". I am not rich and I cannot afford to being doing this every time my mind gives me these thoughts.
