Can't take another picture on my iPhone?

I have 82 pictures, 0 videos, 163 songs, but 29 apps. My iPhone says it doesn't have enough memory to take another picture. This is getting ridiculous because I feel like I'm deleting pictures and apps and texts every week to save memory. Is this normal?

Added (1). The ones that consume the most memory are Instagram and my Music. Also, most of my apps are photo editing apps so does this have anything to do with it?

No. See if you can schedule a appointment at apple to check it out. If you can.

Checkout the usage section of your iphone to keep track of your memory space, see if you can delete apps that consume the most memory,
yes if music and photos apps make up most of the storage than you will have to either delete some music you don't listen to or delete photos apps or the files contained in the photo editing apps to free up space

Hmm thats not that much, you need to check it and see where all the usage is.
