Women's Clothing (Rio Chama)

I'm looking for women's XL clothing. Such as blouses, t-shirts, pajamas, pants such as leggings, jackets, coats, socks size women size 6-8, slacks, dresses, etc.
I used to wear a women's medium until just about 6 months ago I started gaining alot of weight out of no wear and all of a sudden. I had some labs done and I soon found out that I have a slow underactive Thyroid which is the main cause of the weight gain. I'm a single mother of two young children and most if not all of any income that comes in goes to taking care of them or bills. Leaving no money left for me to buy clothing that fits me now that I'm wearing an X-Large. I don't have hardly any clothes that fits me right now and I'm kinda in desperate need of some larger clothing. I'm not picky at all and will take any women's X-Large or bigger clothing right now. I'm constantly washing my clothes as soon after I wear them causing my electric and water bill to increase. I'm already struggling trying to support my 2 sons and myself and I can't really afford for my bills to increase like this. Please if anyone can help I would appreciate it and I would forever be grateful.
