If you really can't afford the treatments/don't have insurance/etc, there are often many clinics/offices that offer sliding scales for therapy or free services based on income. Also, depending on your income, you may be able to get medication for free or a highly discounted rate by applying to your prescribed medication's manufacture. Doctors can often give samples so you can see if the med actually works for you before applying, too. Also, if you still go to school, many colleges have mental health facilities that they often make available for free for a number of sessions.

It sucks that the cost of mental health treatment is so high. I don't have insurance either, so I understand what stress you are feeling.
