How to stop acting this way?

I've acknowledged that I'm a brat. My depression has made me realize this. I get mad over little things. I cry for little things. I had to switch my phone to something cheap from an iPhone because I broke my iPhone and can't afford a new one. So like I reacted as if the end of the world and if I'm a loser. I hated how I reacted and I want to change this about me. I dropped my groceries and my eggs broke and I'm angry as hell. I argued with my mom and I'm pissed at how I couldn't just **** the eff up, I hate myself for talking back. I can't control my anger. I try to be optimistic but I'm still mad how can I be control?

Can I get old text messages back that were from a past iPhone that includes pictures that were sent and received in the text messages?

I've had the same phone number and same phone service for the past 8 years and on one of my past iPhones I've had has text messages and pictures that were sent and received through the texting that hold sentimental value and I'm looking to see if there's any possible way I could get them back? Any pointers helps and I thank you to whoever can reveal this information.

What iphone should I get

So i'm debating wether to get the 6s, 7, or 7+. The 7 is only 3$ more a month than the 6s but the plus is like 8$ more so it's pretty expensive. My dilemma is because of the headphone jack because I love to have it but the 7 has very good quality and the plus has even better quality. I know i could get the charger splitter thing but that would b kinda annoying. Is it annoying to have or is it fine? I love to take pictures so that would be really good for the 7 but should i get the plus even tho it's more expensive like is it really worth it?! AGH i just need help deciding which one is really worth it!

Phone or internet problem?

For the last month or so I've had an issue with accessing the internet on my phone (an Iphone 6).while connected to my home's Wi-Fi network. Every other device connected to our home Wi-Fi network works perfectly fine, and my phone also works correctly when connected to any other Wi-Fi network I've tried (places like starbucks, friends houses etc.). To clarify, my phone will say it is connected to out Wi-Fi network, but I can rarely access any sites. I don't know if it matter at all but we have wave broadband.
