hello someone help

No problem. Ditch Farcebook t***ter Toktak and any other social media. Get a haircut like you were in the Army. Buy a suit or three. Polish up your CV and hit the Employment agencies. Think why you want to work. When you get an interview do some research about the company. Ask intelligent questions seem genuinely interested in widget management or wotsit manufacture. Be polite attentive and engaging. If questioned about that Farcebook post of you and your mates off your head on chemicals at Glastonbury. Say your account has been hacked. Claim to be a completely different person now etc. Bone up on answers to the usual questions "where do you see yourself in five years time " etc. Realise that the people interviewing you are also nervous and don't know what to ask you. Which is why you get daft questions. Be prepared to start at the bottom and work your way up. Oh and be punctual always. Be honest if you don't know something ask. Best of luck.

"....however I messaged the manager on facebook and told him I was too good to work there and my application was removed."

What did you do that for? If you are going to score own goals like that, you certainly need help. But this isn't the place to look for it - sorry.
