help me stop the madness

I about 6 weeks.  And I stop for a day and half. Then..... my mom was around me a stressed me out.  Had me lifting and doing other things. Grant it she doesn't know. But even if she did I don't think it would changing.  She is the type to say. When I was pregnant I did this or that and always some negative comment. With this being said how do I stop. Help.  I really feel guilty and want to but sooooo stressed.
