I would not recommend Prozac, or any form of selective serotonin reuptake inhibitors for that matter. While you may see temporary improvement from taking such psychotropic drugs, they are not going to address the actual root cause of your depression/suicidal tendencies. The cause, most likely, is a serotonin deficiency. SSRIs work by conserving existing brain serotonin supplies by keeping more serotonin in the synaptic gap between neurons. In essence, they recycle your brains existing low levels of serotonin, but do nothing to enhance it.
Your brain produces serotonin (known as 5-hydroxytryptamine), by the conversion of the amino acid L-tryptophan to 5-hydroxytryptohan, which in turn is metabolized by the liver into serotonin. There are numerous reasons why your body may not be getting enough of these amino acids, but in any case, the best way to increase your brains supply of serotonin is by actually taking a supplement containing this amino acid that is the body's direct metabolic precursor to serotonin itself. This supplement would be 5- hydroxytryptophan (5-htp).
There have been numerous trials and studies conducted on the effect of taking this supplement for depression, insomnia, fibromyalgia, and even obesity. Most of these studies have been conducted in Europe (most notably by Professor Federigo Sicuteri at the University of Florence), where natural remedies and herbal supplements aren't considered taboo, as they usually are here in America. Interestingly, after conducting a series of double blind studies, those taking 5-htp saw a marked improvement in their mood and behavior, more so than those taking commonly prescribed SSRIs. This is all referenced by Dr. Michael Murray in his book on 5-htp, if you are interested further.
The reason we don't hear much about this supplement is most likely due to the fact that it is a naturally occurring substance found in nature...a plant extract in fact. You can't patent nature, at least not yet. Therefore, the pharmaceutical industry won't spend the millions of dollars necessary for effective trials and studies of the drug in order for it to be considered a viable alternative to modern antidepressants. There's just no money in it.
Aside from the fact that taking such a supplement will actually address the root cause of your condition, rather than just put a band aid on the symptoms, taking such a supplement is a much safer alternative than an SSRI, with little to no side effects. It is also considerably cheaper, with no prescription necessary, as 5-htp can commonly be found over the counter at any health market or pharmacy.
I also notice you say you sleep 14 hours a day? I am willing to bet that even after those 14 hours you probably still feel tired. This is most likely due to the quality of your sleep, not the quantity. Another thing that 5-htp helps with is sleep. Serotonin is the precursor to melatonin which is involved in sleep cycles. In short, by having more melatonin available you will experience more cycling and spend more time in the restorative, REM, stage, and Non REM deep sleep stages 3 and 4. You will find yourself dreaming more and feeling much more refreshed with less time spent asleep.
Here is a useful article comparing 5-htp to Prozac.

Anyway, just thought I'd offer up a contrary opinion. Maybe run it by your doc and see what he thinks, although I'm sure he'd be much happier writing you a script for Prozac then telling you to find a "natural" way of curing yourself.
