dont be discourage keep on applying. i had the same predicament as yours when i came here five years ago.
First thing to do is to ask your self what kind of job would you like.If you are thinking of a job which you had back in the Phil.(your profession in Phil.),you might find it dificult to apply for that job coz most of them will be looking for UK work experience. Your work experience in Pinas has no merit. If you really want to practice your profession here in UK, my advice is to study again here while working if you can manage.
But If you want a job right away the best thing to do is to go to a recruitment agency, then look for jobs which you think you can do. some of my friends work in factories, some in warehouse, some in restaurant, etc., you can do part time or full time job, whichever you prefer.
hope this help
