I had an acute onset, similar to yours (but not quite as bad) about 3+ years ago. Things stabilized, then got somewhat better over a few months, but I do continue to have some relapses now and then and things get worse for a while. Just make sure you go back to the things you think may have helped you initially, and hopefully things will get better again.

Unfortunately, this is a bit of an unpredictable disease that we are battling. I hope you get back on the road to improvement soon.
