I am so upset

i brought 50k traffic in the hope of growing my site to a decent level of traffic thus earning some £££'s but it has all gone to nothing. the highest the sites traffic has ever been was at 27k now it is at 14k
i get told alot of the time, never give up, thing will work out etc. but for some reason it just doesnt seem to work.
i have tried everything to get traffic to the site. i need to start earning cause my overheads, for example hosting costing money that i simply have not got.
if anyone could help me out with my site then please contact me on icq 309196660 i would appreciate the help.
