Hi and Welcome to the Community!
Anytime random strange behavior or sluggishness creeps in, the first thing to do is a battery pop reboot. With power ON, remove the back cover and pull out the battery. Wait about a minute then replace the battery and cover. Power up and wait patiently through the long reboot -- ~5 minutes. See if things have returned to good operation. Like all computing devices, BB's suffer from memory leaks and such...with a hard reboot being the best cure.

Hello...and sorry for the late reply!
I therefore recommend that you attempt to boot into Safe Mode:
It may take you multiple attempts to get the ESC key sequence (press/release/hold) correct, so be patient. When successfully into Safe Mode, think carefully...what happened just before this behavior started? A new app? An update? A Theme? Something else? Think carefully as the smallest change could be causal...and attempt to undo whatever that was.
Further, is there any chance your BB got wet? What you describe could be caused by that...if so, then
REMOVE YOUR BB BATTERY NOW!!!
Run, don't walk, to this FAQ:
Do everything it says, including waiting the maximum recommended time. Applying power to your BB between it getting wet and doing this process reduces the chances of success. Further, the only thing predictable about moisture intrusion into a BB (indeed, any electronic device) is that the results will be unpredictable. I've seen some come back up right away and be fine. I've seen others never work at all. I've seen still others run for a bit, and then die later. And every thing in between.
Good luck and let us know!
