My life is in such a mess and i dont know where to start?!?

Ive recently stopped smoking marijuana after 9 years of abusing myself with it,im 27 single and i havent had a girlfriend for 2 years and even that only lasted 3 months she dumped me because i wouldnt quit the weed and i said some bad things when i was drunk i havent had a job since may this year that only lasted 3 months too,my best friends arent really my friends anymore we still keep in touch but they are so involved in thier own lives i hardly see them anymore maybe once every 2 weeks somtimes longer but my closest friend still txts me every few days and i somtimes go out drinking with them ,ive made other friends but they turned out to be backstabbers so i told them where to go.Well since i have stopped smoking it i feel better and i have a bit more confidence in myself,ive cleaned myself up and i dont look like a tramp anymore,theres 2 things i want a job and a girlfriend but because i abused the weed for so long its messed my confidence up and gave me anxiety.Some days i dont even have the confidence to phone for a job because i think whats the point,they wont want me because my CV sucks and sombody else will get the job and they wont want an ex drug addict working for them,they dont have to know that but its in the back of my mind all the time.Even when it comes to girls ive had plenty of opportunitys since my last girlfriend to date other girls but i was still smoking the weed and the anxiety keeps telling me that they deserve better than me and if i talk to her she going to think im a freak.I know its not really true but its the anxiety putting things in my head negative things about myself.My head isnt totaly messed up, reading this i bet i sound like a right freak? All i need is a job or girlfriend to give me some hope that i can still change my life,im really lonely too : ( been lonely as hell for 2 years.The only thing i have going for me is ive been learning how to dj/and produce on my pc for the last 2 years and im getting really good at it.So whats the priority a job or a girlfriend? Without a girlfriend i feel lonely and unwanted and i just get abuse from my friends for not having one the best they can do is call me gay,they know im not so why are they trying to fcuk with my head even more? Without a job i have no money and i cant do anything.I have all this pressure on my shoulders and i dont know where to start,whenever i find a vacancy for a job i dont hear from them i was lucky with my last job but that was only a 2 hour a day cleaning job anyway and i worked for a bad company.
