Would getting more GB on my i phone make my I phone act normal again??(SEE DETAILS) (PLEASE HELP!? 10 PTS)?

[Skyler L]

I cant even update to ios 7 because I have no gb left on my phone I know the main reason is because I have like 14,000 & something pictures..I'm a picture hoarder & I love taking pictures Its really hard for me to delete pictures & also, I dont really wanna delete my pictures.I can't even open up my camera anymore because something pops up & says I need more space..I've even deleted all my music & all my apps & I still have 0 gb..I have like frozen apps on my home screen from where I tried to update them but I guess they could never load So im actually not even able to delete those apps (its about 3 ) there just there frozen & when I hold my screen to delete they just stay still and dont wiggle & I dont get the option to delete them...Sometimes my sister sends me text & I don't even get them unless i delete like 10 useless pictures..Same with youtube on safari the video will not even play unless I delete a few pictures..My phone says I have 0 gb even when I do delete pictures..Do you think buying more gb would help my phone I just have the regular average lowest amount of gb on my phone well I had that many to start with.Oh & if anyone was wondering I take my pictures with Instagram (my only app) which saves them to my camera roll since I cant open my camera..I cannot get anymore apps either?
Also, If anyone knows how much it would cost to buy more GB could you please tell me (I have an I phone 5) not sure if that matters though
