My bet here is that some Slashdot posters are going to enter this conversation and tell you that you don't need a CS degree to be successful. That you might even be able to get away with taking a few formal classes, working on some more open source projects, and to keep trying. That you can somehow salvage your situation and make something of yourself in this field.
I believe this to be true, but only in an outlier sense... statistically your current situation does not put you in a favorable light to be hired. There are surely people who got into computer science through unconventional methods - but there is always a common driving force behind their efforts. They don't end up being successful with computers by accident, they have a long history of psuedo-study that has given them the ability to be competitive in the space.
To put it bluntly, why should I hire you? You've got a soft-science degree which frankly many people don't respect. People with Masters and PhDs are working in bookstores right now - and you have a basic Psychology degree. This shows a lack of planning on your part that I would hold against you on an interview... and to be clear: I do a lot of interviews. You would never make it to me as our filtering process would eliminate you along with the bus drivers who are also applying for jobs with us (that actually happens, pretty amazing).
The economy of the situation is clear. There is a huge swath of unemployed people right now with more skills than you, with more experience than you, with better training and a more appropriate degree (lots of EEs are unemployed for example). So it's going to be really tough for you to sort of slip through the cracks and get a job. Is it possible? Yes. Is it likely? No.
If you are truly interested in getting into the field, you should consider that at no other time has it been easier to be an independent developer. Work for yourself, make your own projects. Make some games for the apple app store (forget android, so hard to make money there) or something, and get cracking.
