Monerod finished syncing but now never catches up in GUI wallet, monerod still syncing

Question

I'm using Windows 7, 64 bit, on a crummy burner laptop. So monerod finally finished syncing last week and I followed advice here and opened the GUI wallet, it was all syncing together as it should but literally only for about an hour - after that monerod never stopped adding blocks, coming up with the 'new top block candidate' message. I had to leave it overnight and when I came back it was way out again, only by 7 days but that's eons on my old machine and slow connection. It's been the same for a week now, it never catches up to the top block and the wallet constantly says syncing to the daemon. What am I doing wrong? I just want to use my wallet but this is about 4 weeks building it now. Everything has gone right, just that it's taken forever to do so. Because it was synced at one point is it ok/safe to use now? Or do I have to keep waiting for it to fully sync with that never-attainable top block? Thanks for the help, really appreciated, and my apologies if this has been answered but I can't find the answer to this on here, maybe I'm being blind or stupid or both. I am useless at this stuff, I've followed the guides here and reddit to get this far with a lot of trial and error, never fully understanding what I'm actually doing. Yep, it's bad... Thank you!!!!!!
