I would stop the partying and the drinking. Cut up your credit cards. Do your own personal SWAT analysis.
Write a resume, brush up your interviewing skills, and start applying to all sorts of jobs, ones you would like and not like. The point is to get an income stream.
Learn to save. Learn to budget. Try to live such that you are keeping your head above water and can pay off that debt. And this might require moving into the shallow end of the pool. In other words, if you have to sell/downgrade your car to afford less (or no) payments, do that. Can you use public transport? Do you have/need a fancy cellphone/plan? What about cable TV? Eating out all the time? Gym membership? What monthly expenses can you do away with? Move into a smaller apartment? Move home? Get a roommate to share the rent? Cut coupons? Sell any fancy gizmos you don't really need?
Start paying off that debt, treading water, and then eventually start saving/investing again. Once you get control of things, start looking for better jobs, etc.
I too fear the societal push to get married, have kids, and have a mortgage by 30. But guess what? You can still earn an honest living, be debt free, 30, unmarried, no kids, no mortgage, and still have lots of fun in life.
I am afraid it is time to grow up and get responsible. But that does not mean the fun stops forever. Fun just takes on a new definition.
