Lack of pleasure and enjoyment in life, and antidepressants are keeping me stable, what shall I do?

Stay the course. The goal in treating depression is to return to normal. You don't want to just be better, you want to be well. Antidepressants should be continued for at least 9 months after all symptoms have resolved. The decision to continue or not continue antidepressants should then be discussed with your doctor.
