Feel trapped in job

Originally posted to PI, would be better here though:

Some history on my situation first:

I've been working in the same multinational IT company for about 20 years, ever since I finished college. I don't have a very senior role, but up until recently I was happy enough with my job. The salary is decent, mostly because of how long I've been there though.

About 2 years ago my department was moved to another country, and bit by bit most of my colleagues started to be made redundant. Eventually it happened to me too, and I was offered a very generous payment (1.5 years' salary), and 3 months garden leave.

I spent about 8 weeks job hunting during this time, and doing a small number of interviews. I realised at this time that getting a job in my field would take way longer than I thought, and I would most likely take a large paycut.
I saw an opening in my old company for a job that I could probably do, but was far from ideal. I panicked though, went for an interview, and got the job.

Now it's almost 2 years on. I am not keen on the job. The work itself seems mostly pointless to me, but the quotas/ targets we have to achieve are what I really dislike. I would love to do something else, but my brief period between jobs is really making me think twice. I would be crazy to walk away from such a big severance pay (should it be offered again), and the drop in salary would mean paying rent and bills would be a huge struggle.

I'm sure I'm not the first to be in this situation. Are there others who have been there and done something to get out of it?
