Why am i and how can i stop being so mean to people esp to those i love?

Lease help me! I'm such a mean person and although i try, i can't stop. I'm so mean to my parents. They give me everything and love me so much, yet I'm just so rude to them and this makes me really sad. I'm a 17 years boy, the youngest of my siblings and whenever I argue with my parents, ESP my mother, I say some very cruel things that I end up regretting but I can never manage to apologize (I'm too cowardly). Also I feel like the main reason behind my cruel misdemeanor is that I have been spoiled for so long that I don't realize how lucky I really am to have them and i take eveything they give me for granted. Basically I would argue with my parents for the stupidest reasons and criticize and blame them for everything. I'm also really short tempered and impatient. Once when my mom picked me up two hours late from school, I was so angry that I started cussing at her with the meanest words I could thing of. I also yelled at her when she accidentally poured water and hence ruined my history project. And for my dad well i insult him everytime we reach an argument. I criticize his job, his clothes, and everything. I really wish I wasn't so spoiled cuz if I wasn't I probably wouldnt be such as dick. They give me everything (if i want a new laptop they give it to me, if i want a new iphone they give me it to me) and are just so lenient towards me. They always try to make me happy, yet i bet i'm a huge disappointment to them. I get poor grades in school and i'm the worst kid a parent could wish for.sometimes i wish they actually disciplined and hit me whenever i do something wrong so i can actually learn to behave. I also wish I wasn't so mean to other kids in my school. I'm a popular kid at my school and well anyways my best friend who is a real jerk would always tease these so called unpopular and ugly girls in my school but I can't help but feel really bad for them but I don't do anything about it. Instead I pretend to laugh alongside him and my friends but deep down I feel really guilty. There was also this one really sad, lonely, and mentally ill kid who would always talk to me and wanted to be my friend, yet i would always be mean to him whenever my friends were around. I feel really bad for him though cuz he just looks so sad and lonely all the time.lastly, I'm also so cruel to my girlfriend. I would never hit her but I do say some very mean things to her when I'm angry. I always call her stupid and ugly and make her cry when she is really the nicest, smartest, and most beautiful girl i know. It tears me when she cries, but i never try comforting or appologizing to her (cuz again I'm too cowardly). She deserves someone much better than me. I just hate it how I'm so selfish and mean to everyone.everyone in this world treats me so well yet i treat everyone so badly. I'm so lucky to have such a kind and beautiful girlfriend and a loving family; however, instead of returning the love they give me, i make their lives a living nightmare. I'm so depressed right now and i cry almost everyday because of all this and now I feel like just killing myself because my family, girlfriend, and the world would be whole lot better without me. I talked to my counselor about it and she said i might have an extreme case of bipolarism.

Does whipple cream and silicone air dry?

I want to start making polymer clay and deco-den phone cases. Since I'm a beginner I obviously don't know much, this is an example of what I want to make:

http://www.etsy.com/listing/162828144/cute-bunny-iphone-5?ref=pr_shop

So what I want to know is:
Does whipple cream and silicone have to be baked?
If they have to be baked what type of decorations can I put on as in what type of material?
Can I put glaze to make it shinier?
Do I have put crazy glue on the decorations to make then stick?
Or does silicone and whipple cream air dry, and the materials just stick on once you put them on?

Wouldnt this be great if it happened?

So there's not many jobs here in the US but if these major companies such as nike, apple etc. Would bring over there factorys from china wouldnt there be many jobs for americans here? I mean if you put these factories all over the US, that would slow down crime rate and would better the cities. Ofcourse that would mean that things would cost more but hey people will still buy iphones, shoes etc. On a daily basis no matter how expensive am i right?

How to mass delete camera roll?

I have an iphone 4s and i just need more room. I have 19000+ photos of random stuff. How can i do a mass delete.things i have tried iexplorer (keeps images only changes them to bad quality), using the sync option on itunes (did absolutely nothing), and for some reason in my "computer" menu my iphone isn't showing up. What other options are their.

Added (1). I also have some other stuff on their that i wish to have stay so i would prefer to not refresh it

Added (2). I don't know what is wrong with my phone though. When ever i unplug it, that's when the computer decides "oh lets try to install the software now.whoops looks like you unplugged it.guess i can't install it." and it will never attempt to install if its plugged in so with this being said i can't even access the iphone menu from the computer section.
