Renew it.
If you don't renew your professional qualifications now, you'll look back and see this as the pivotal point of when you gave up. And what will be the trigger that makes you eventually renew? Seeing other people in your shoes getting jobs? Jobs you could have had?
When the job opportunity comes, you'll need your ME-IR and will curse yourself for not renewing.
Good luck with the job hunting, and hang in there.
