What's wrong with my iMessage on my iPhone?

The contact set as me was messed up but I fixed that and the messages still won't work. Whenever I try to send something to my mom, I receive a message from myself of what I just sent ad IIm not sure if she s getting the message at all.Also, someone sent a message to her and I received it, but she did too and I just have no idea what's goin on with our phones. My mom also just got an pHone 6+ and that might be why they re messed up because we all use the same apple account but I don't know how o fix it.

I use to be able to go 3 days without charging my iphone 6 now I have to charge it every hour or depending on how long I stay on it.

My power keeps going out but when it does so does my iPhone why is this happening?

I live in Raleigh NC and lately it's been really hot I mean we've broken temperature records like everyday. I already knew that heat could cause power outages but yesterday I was on my phone and the power went out but so did my cell phone. The power came back on a few seconds later so in turn so did my phone. I didn't think much of it but then it happened again like an hour ago. I didn't have my phone plugged in so it wasn't a power surge could it be the the kind of phone I have, I have an iPhone 5s. I'm just really curious to why this keeps happening so if you know please lay some knowledge on me.
