PLEASE! Send help needed to find very large winter wet suit

Hello. I am an open water swimmer in the Northwest and can't bear not swimming in the lake anymore. A couple weeks ago it was fine at 63, but it's getting colder, and in winter is about 48. Problem is I can't find a wetsuit; I'm short and heavy and don't see anything in my size. In womens' clothes I wear about a 20 or 22, i am 5 foot 3; and in bathing suits like Speedo can wear swimsuits in size 20 or 22 also. I'd like to swim in water as cold as 48 this winter. Any suggestions out there? I looked online; they have XXL men's but not women's it seems.
