Yes and no ! When you brought the bird home with you , you took and changed the birds entire world, it no longer has anything around it that is familiar to it and this is a terrifying situation for a lone bird that depends on a flock to provide it with safety and security. In this respect it is normal, but this should not have gone on for so long, that is not normal. Have you closely examined the birds food dish to see if what is there are whole seeds or just the husks of the seeds? Budgies, like the larger parrots do not eat the hard outside casing of the seed the crack the seeds open and only eat the softer, more nutritious kernel.
Your bird's cage needs to be placed so that the highest perch, the one that the bird would sleep on is about eye level when you stand next to it. Ideally it should have one side along a wall and be close enough to a window to benefit from indirect light from outside.
Now it is also possible that you have a sick bird, so you should take it to a vet right away for an examination and also discuss this with the vet. If you have the space for it one of the kindest things that you can do for your budgie, if it checks out with the vet is to get it a companion of the same species and of the opposite sex. These little parrots scare very easily and having a companion or a mate will greatly reduce the stress on it.
