var wholemessage="<p>I&rsquo;m a college student in Minnesota, and I lost my shirt quite a few times when I used to gamble.  <nobr>And I used</nobr> to gamble a lot. So much that my life was pretty messed up. I dug a pretty deep hole, but I consider myself lucky. I got help for my gambling problem by calling 800-333-HOPE <nobr>(800-522-4700 outside of MN).</nobr> Now, I haven&rsquo;t gambled since my sophomore year, and my life is back to normal. I built this site to tell my story and to help other students who find themselves in a similar situation.</p><p>My gambling problem didn&rsquo;t start because I was a bad gambler. I&rsquo;ve been playing poker since eighth grade, so I knew what I was doing.</p><p> I won lots of money from guys in the dorms, but the stakes were pretty low. On a good night, I&rsquo;d win maybe $30 or $40. On a bad night, I&rsquo;d drop about $20, tops.</p>"
//wholemessage=wholemessage + "<p>My problem really began when I started going to casinos with my friends. We&rsquo;d hit the buffet, go play blackjack and video poker for a couple of hours (or until we ran out of money), then come home. But one night, I snuck out of the dorm and drove back to the casino by myself. I stayed there all night, but at least I won back what I lost earlier.</p>"
//wholemessage=wholemessage + "<p>Before I knew it, I was going to a couple of different casinos several times a week. I started skipping classes&hellip; overslept a few lectures. I rarely hung out with the guys anymore. And my girlfriend dumped me. Before the end of my freshman year, I managed to lose all of my savings plus the money my parents sent me for the summer. I had no money left to pay for rent, food or anything else. So I sold my guitar, CDs and other stuff. Thinking I was always just one big win away from fixing everything, I took cash advances on my &ldquo;emergencies only&rdquo; credit card until I maxed it out.</p>"
//wholemessage=wholemessage + "<p>Now don&rsquo;t get me wrong, I had some big wins, too. I had some $1000+ nights, and one time I was up almost four grand. It&rsquo;s just that I didn&rsquo;t   know when to stop when things weren&rsquo;t going my way. I found out the hard way that gambling isn&rsquo;t a matter of skill. When you win, it&rsquo;s dumb luck. And when you lose, well, that&rsquo;s just the casino&rsquo;s built-in house advantage. I also realized that I couldn&rsquo;t control my gambling by willpower alone. That&rsquo;s when I lucked out and found help by calling <nobr>800-333-HOPE</nobr> <nobr>(800-522-4700 outside of MN).</nobr></p>"
