Should i get a phone?

4 my 13th birthday i wanted a phone but i have NO friends to text or call so there is really no point but i want a phone to call my mom if something goes wrong and i can call my cousin to see if she can come-over and if i do get a phone what kind? it has to be from sprint and has to have touch-screen, camera and i would like a QWERTY Keyboard and PDA/smart phone but i only have 3DAYS to pick or to get something else
