Why won't my IPhone 4 turn on at all?

(My IPhone 4 had been bought on EBay and I have had troubles with it before)

I had being using my IPhone 4 earlier and it was working fine. The battery was on 20% so I knew I needed to charge. My sister wanted me to help her with her homework so I left my phone not charging. After about 10 minutes of helping my sister I came back to get my phone. Once I came back the screen was black and won't turn on. I have left it charging all night and nothing is going on. It makes a messed up noise when my sister tried to call it but that is it, I tried calling it again this morning and nothing happened.

Being a writer I write on my phone on an app. I had not backed it up on I cloud as my phone's I cloud doesn't work. I have about 6 stories with at least 4 pages of writing in each. So I have a horrible feeling its all gone.

Apps keep closing and Voice Control Keeps Popping up on iPhone 3GS?

I recently got an iPhone 3GS and the Voice control keeps popping up for NO REASON! How can I permanently disable it unless I turn it on. Also, I can be through half way through a text or on a game and it will exit onto the home screen without me doing anything and sometimes when it exits an app, it will make the home screen go grey and the essential bar (at the bottom) is the only highlighted area!

I have proven myself incapable of getting a job and am desperate, advice?

I have applied to over 2000 positions about 300 in person and the rest online via e-mail over the past 6 months. I would've applied for a lot more in person because I know it shows initiative but the problem is my father whom i live with doesn't have a computer or printer ( I'm asking this question on my iphone) and for me to apply in person I have to print at the library which is 20 cents for 1 side of of ink which for my package (cover letter, resume and references) costs me a minimum of a dollar which is money I don't normally have to spend because I don't have job or any way of getting money and I just can't ask my father because we have been going through hard financial times. It feels like I've done everything. I have accounts to 5 different job search websites, 4 employment agencies have me on file and I call each of them once a week to ask if they found something for me and its the same thing every time "no", I tweak my resumes and cover letters the best I can based on the job I'm applying (which in high school I took a class on how to do) and when I do apply in person I take everything into account from the shoes I wear to the way I dress my hair and despite all this I have yet to have gotten so much as a job interview. I'm so tired of people saying when I tell them this "really, not even McDonalds (or places like that) is hiring" I mean for the love of god the minimum wage positions are the main nuts I have been unsuccessfully trying to crack. It seems all I feel nowadays is frustration and anger over my ineptitude. I'm currently in university (first year), i'm there to pursue my dream but I didn't get the marks I could've gotten because I have been focusing so strongly on getting a job. The reason being this, even if I do manage to get through university on nothing but my father and student loans I'll still be the 26 year old with little experience and not even a job before or during my schooling. My future is on life or death dependence on me getting
