Dealing with Anxiety Tips

Hi IM's
I'm going through a bit of a rough patch ATM with my MIL. She's quite a .... She's staying with us regularly as she's out here from overseas. I Don't normally let this kind of judgmental behaviour of others bother me so much, but I guess because it's in my face more often then not I'm finding it hard to just push her insinuating comments to the side.
She's extremely judgmental of me and has made remarks about my husband and i's relationship, of course it's all very sly, as if to say I'm fake and only with him for $$. My husband is 13 years older than me, were very much in love have been together for 7 years and have a child and house together. It seems nothing I do is ever good enough. My husband sees some of it and by no means would i ever get inbetween everyone and cause unnecessary conflict. She won't be here long and things will go back to normal. I keep telling myself... Not sure what I'm asking, I guess how have you dealt with anxiety. I've never had it before, I know it's because I'm letting her comments consume me and my thoughts, I take a lot of what she says personally because I know she doesn't like me. My husband is really supportive and a great ear for most of the part. But I don't run and tell him every single thing she does or says as I would just look like an idiot and I think that's most of the problem. Is I'm not sharing my feelings enough (so I thought I would vent here). My tipping point was when she told him he should check his bank account regularly to make sure "poor people aren't stealing from him" this really disturbed me. I'm a SAHM currently trying to build a home business for us and to take care of our young son. My husband also pushed me to follow my dreams in doing so but I guess old school mentality and possibly some form of jealously toward us is really causing me a lot of grief. Any tips on both subjects would be greatly appreciative. And sorry for the long winded note, I'm just feeling really down and out that every aspect of my life is criticised with insinuation rather then her just being forthright. Also by no means have I shown her that she is affecting me, I keep my head high and with a smile all the time.
