Dear Bev,
I'm new here, so I hope you don't mind my responding, but there are a few things that I think you really need to know.
First, please try to forget the guilts - you did NOT cause this.
Second, please try to get some outside help for your sake - I don't think there are many people who have the tools on their own to know how to deal with things like this.
Third, please know that there are many different types of lymphoma, and that they are all very different from solid-tissue cancers such as colorectal cancer. Stage IV is just as treatable as Stage I for lymphomas, because they are all systemic cancers. The indolent versions, such as follicular, aren't considered curable, but are considered treatable (I personally know folks who are 20 years past diagnosis), while the b-cell aggressive versions, such as diffuse large b cell, have an excellent prognosis regardless of staging. A really good site for information on lymphomas is
http://www.lymphomation.org. This is a patient website that is science based.
Fourth, there is an on-line support group for lymphomas at
http://forums.lymphoma.com/index.php that is much like this one --- full of friendly, knowledgeable folks who will be there to support you all the way through this.
My first husband passed away 8 years ago from lymphoma and it was the info and support from both of those sites that really helped both of us throughout his illness. He had a very rare type of lymphoma, so please don't be scared that he didn't make it - it's extremely unlikely that your husband has the same type.
I don't have enough posts in yet to send you a pm, but please drop me a note if you want to chat about lymphoma (or anything else) and I'll figure out a way to get back to you.
Sending you strongest thoughts...
