iPhone 6s boot loop (NOTHING is working)

Last night, I couldn’t get any of my apps to load or stay open. I tried just turning it off and back on again but I got stuck in a boot loop. I’ve looked up videos and online guides but nothing has worked. I went into iTunes and updated it, and now my computer isn’t even detecting my phone when I plug it in. I’ve tried all the button combos and every trick I could find (I’ve been trying for an hour and a half now…) but I’m still haunted by the aggravating apple logo. I don’t even know why this started, I’ve only had it for a few months and I haven’t messed with anything that I’ve heard causes this.
