learn to stand up for myself

I seem to never do what is right no matter how I do it….I am so sick of being told to do trhis and do that or why did you do it like that instead of this!!! I want to just say to someone you do it if you donñt like how I do it do it yourself!! Also I am tired of everytime that I have a discussion with my husband I am the one who never knows what I am talking about, so not to end up in a fight I just let it be and let him think that he knows everything and that he is right…..URRRRGGGHHH it is so annoying and makes me feel like I am stupid!!!
