I applied for some internal jobs but I was honestly so ready to leave. Had my job move or be eliminated three times in my 13 years there. Took my seven months of severance and went to a new company.
Keep your options open. If there's an internal opportunity that appeals go for it. Don't worry about giving up the severance; odds are your new job will be eliminated in the next few years anyway.
I can agree with @11NvW7KZ-byw .Good advice
