Ps5 controller issue: left stick shifts to left automatically. What is the solution, or need to buy a new controller?

Yesterday I drop my controller and I am beginning to notice when I’m playing games, or going through the apps, the left stick is shifting to the left automatically. I’m guessing the way it fell the stick inside the controller must had got detached. I even try to reset the controller but it is the stick

What should do? Get it repaired, fix it myself, or buy a new controller?
