Hi Kenandahlia,
Honestly you are right when you are unemployed, you'll have a hard time to convince the consul that you will return after your holiday... unless you have substantial savings or family business and some property docs to show that you have reasons of coming back here in the Philippines...
If you are unemployed, who will finance your travel? then if your friend from UK will do, then he has to prove that he can afford to have a visitor like good savings, stable job and suitable accommodation... ...need to make also a letter of support with your application... If just a friend, need to prove also how your friendship started and how close you are to your sponsor that he's willing to spend lots of money on your on your holiday in the UK...
Best of luck on your application....
