I don't think prozac, or any antidepressant for that matter, is going to change your life in a positive way. What your essentially doing with these pills is making yourself feel better, your not making better, more positive, more efficient neural tunnels; your closing your eyes to the real problem.

I would strongly encourage you to do something that stimulated your brain in such a way as to give you more control over your emotions, a better flow of neurotransmitters, etc, and that would generally make you feel better and be more intelligent. So, you could, for example, learn a skill, i.e. cooking, and get some regular aerobic exercise, listen to music (not dark, aggressive music, as this often causes some parts of the brain to atrophy over time, but light music, be it classical, or electronic, or something along these lines), and write (you could journal as well- I've recently found this to be very helpful, especially when I'm feeling anxious, depressed, angry etc).

If you let the parts of your brain that control these aspects of your personality idle for too long (thus destroying the healthy neural potential), then I wouldn't be surprised if you fell into severe mental/physical illness in later life(i.e. Alzheimers, dimentia).

Be careful how you treat your brain, you've only got one after all.
