sorrelyou have real concerns but based on your work history i don't feel you would be cut at least in the first tier. sometimes i worry too much over something and i find it never changes the outcome. it only adds to my stress level and mental weariness. i don't see any reason why you can't approach your superior for input altho everyone may be concerned as you are. if you have a good rapport with staff and do your work well you've done all that you can do. the rest is out of your hands. hopefully my post will ease your mind some. worrying will not change the outcome whatever that is and whenever that is.
it sounds like you have a good head on your shoulders. just enjoy each day and wear a smile. the only other thing i can suggest is to be cautious with any extra spending until you know what's what. that's about all the planning you can do right now unless you want to apply for some other jobs to see what's available. if nothing else it will give you interview experience in the event you find you need to obtain a new job. that will keep you sharp in the meantime since you haven't probably interviewed in 7 years. who knows maybe your interviewing will bring you an offer and you'll need to pick which job you want! best wishes.
