Depo shot. Side effects?!

Depo shot. Side effects?

Tomorrow I will be getting the Depo-Provera shot. I chose this method of birth control because of its convience and its effectivness (99.7%). However, from all the sites I've visited about this shot, the side effects arent to good. The bone loss, irregular period, abdomenal pains, and all the other side effects are makin me worried. Has anyone had this shot and gotten any of these effect?

I was on it, and I was miserable the whole time.

I gained 5 lbs every time I got the shot, even though I didn't change my eating and exercise habits at all. I tried to stick it out, but I gave up after I hit 40 lbs of gain. I know it was the shot, because I lost the weight after I got off of it. My breasts were too tender to touch and I lost my sex drive (with interferes with the whole reason of getting the shot). I lost hair by the hand-fulls. My skin broke out horribly. I was always mean and grouchy. I knew it, but I couldn't help it. I started slipping into a depression, too. I only got a period once every three months, but my friend bled all but one week every three months.

Yes, most other forms of birth control have some side-effects, but they are not nearly as severe. They also go away as soon as you stop, whereas depo can take over a year to wear off. If you do decide to go on it, you are not recommended to use it for more than 2 years because of the bone-density effects.
