+1 on all the comments about looking for a job now vs. 5 months severance.
Also, +10 on continuing to do a good job. No need to be a super hero but remember every day that you are managing your brand. Many years ago I went through a corporate transition where a number of people wound up in the "stay until we tell you you're done and you'll get a big severance check" situation. It was a big check (1 yr with benefits) so sticking around wasn't a bad idea, but some of them got very jaded after a few months -- a few to the point of being malcontents -- which was unfortunate because they were really excellent people. Its unfair, but their attitudes during that transition have haunted them for 10 years among certain people who have moved on to bigger things in the industry.
Always manage your brand.
Good luck.
