Im depressed and i feel nausea .?

So is this a normal sign of being depressed ? Im on my monthly gift, 15 years old. my arm was somewhat achy for like 2 days, sometimes on and off. I believe im hypochondriac. i lift my arm up it hurts in tha upper area. I just feel really down, i feel like i want to cry. I feel so sad, I know im ok but im just depressed. Any ideas?
