Even with degrees where companies are hiring you can still have difficulty getting a foot in the door. Since you have one degree I would look at what you like to do. Take an assessment of skills you have and see if you can find something you like from that. I know that is very vague. What color is your parachute would probably be a good resource for you.
Volunteering is a good start. Maybe you just need a marketing plan for yourself

connecting with professional groups on linkedin or on meetup are good ways to get tips and meet people. Who knows you might hear about a job. Any sort of temp job in a pr firm can work sometimes. I don't know much about that career field so those are very general suggestions. What about political campaigns. Volunteer for that and maybe you have a foot in the door when primaries heat up.
