Life just isn't fair and I tried so hard to turn my life around but it was all for nothing

I used to have a full time job but then I got my life messed up with a Junkie GF and at the end she went to rehab and now live in a Halfway house and I got fired from my full times job and got couple felonies charges. Even tho I was accepted into a conditional discharge program that I only have a few months left to complete it. I have been staying clean and outta trouble. I have been looking for Jobs everywhere, there was couple jobs that I was told I was hired but they need to conduct a background check, but its been months I still haven't heard anything back yet not even a drug test date or Orientation. I guess pending charges on your criminal background is something that employers frown upon, I have been arrested but I was never convicted. I just wanna be given a second chance to start over and turn my life around, but now I have no income, my unemployment benefit been exhausted, I have debts thats around couple thousand. I can't even continue my SNAP food stamps benefit anymore because I am not currently on any training program or in School. I have run outta every possible options. My parent are fed up with me, all my old friends just turned their back on me and want nothing to do with me. Life just isn't fair and I may not have dealt a complete shit cards from God, but I just don't think there is any future left for me. I guess struggling at this point is pointless. I have even tried to earn money legally whenever I can, I test drove a Toyota car a months ago, I was suppose to receive a $50 VISA gift card that could help me out big times, but it never come in the mail......I am just so sick and tired of my life at this point...Its not worth living anymore if every time I tried to take one step forward, then always being pushed two steps back....There is only one thing left in my mind, thats how I can leave this world painlessly.

Update: Tomorrow I will be getting my renewal of benzo medication and I am gonna buy a large quantity of alcohol, so now I just need to look for a secluded place where I can possibly end it all without anyone able to locate me until I am OD for good
