Check out the last post in the "sticky thread" at the top of the forum's main page (it's titled UC resources, or something like that). I submitted a post to it last week with a link to a website that gives links to patient assitance programs for drugs used to treat UC. There is also a link to find free/reduced cost clinics, if you need to see a doctor as well.
Also, you should probably look into COBRA, so that you don't have a lapse in insurance coverage. Once you find a new job, you could have trouble getting insurance due to having a pre-existing condition if you have a lapse in coverage.
