Write a cover letter for your resume. Address it to Dear HR Department. Do NOT put a picture on your resume. Tailor your resume to the job for which you are applying. Delete the content which is not relevant - like your high school clubs.
Research the company. Don't study the website - google the news and the leaders. Prepare yourself to answer tough interview questions. They want to know if you can reason through a tough problem. Listen very carefully and answer all questions briefly but completely. They do not want your life history - they just want to know if you can do the job with dedication and excellence.
Stand in front of a mirror and practice your answers until you can speak with confidence. "I have a wide variety of interests currently." or "I will do my utmost to support this team's goals." Hold your questions until they ask you if you have any. Then ask them "How are you organized here?" or "Who would I report to?" as well as "How much travel is involved?"
Start your Linked In profile. Connect to people in fields that interest you. Build a network. Join groups that interest you. Search open jobs on LinkedIn and Facebook. Use the people you know to meet more people in your chosen field. Research the kind of questions employers are asking now.
Read and reread "How to Win Friends and Influence People" by Dale Carnegie.
Employers need good honest people or they can't run their businesses. But they are inundated with applicants for junior slots. Keep at it. There is a place out there for you. While you are waiting, take an online certification course which is relevant e.g. a PMP or a technical certification. Study MS Office. Join a professional society and go to their conferences with a student discount.

Set a budget for rent - it should be about 25% of your net pay (take home pay). Your landlord will pull your credit report, so pay off your all credit cards the month before you apply for a lease. Car loans or student loans may keep you from qualifying for a lease. You will probably have to commit to at least a year on most leases. Short term furnished rooms may be available near work. You may have to share a place or sublet a furnished room until your credit card debts are paid down. Find a rental on Craigs List
