Is passion dead?

Hi guys. I've been qualified for 3 years and have an immense passion for advertising and copywriting (or I would not have studied it), but no-one wants to give me a shot! I've been trying and sending my portfolio work (recently updated I must add), but yet nothing! Is there any way I can do some freelance writing, or any advice on how I can secure a position in the field that I love? Appreciate it guys!
