First things first! There is NO MAGIC PILL.
One pill will not fix everything. There will be bugs every now and then.
Remember that Anti-Depressants are more of a crutch. The rope without the horizontal bars on your rope ladder to make your climb to happiness.
My suggestion is research the medications, research the psychology or at least the process of how the limbic system, more specifically how Neuroreceptors and Neurotransmitters work.
All of the medications are based on hormones. (Epinephrine, Dopamine, Serotonin, Norepinephrine, Melatonin... You get the idea.) These pills block the flow completely (MAOI's) which are very dangerous, and Reputake Inhibitors (RI's)
RI's are usual the ones prescribed. (SSRI, SSNRI) Reputake Inhibitors literally do what they say they do. Your hormones are blocked from being re-absorbed. So it's a one time use; your body makes more of it for your brain which in theory is supposed to allow better function.
There's another step between but I'll leave them out, they're older and aren't used much anymore.
However this is where I leave you to do your research!
You should look up the individual effects of the pills, side effects, the actual effects of the hormone itself and decide upon which YOU feel is the best for YOU. That was the biggest mistake I made, I didn't say a word when I was prescribed, even after I did my depression presentation. If you'd like a personal experience; I've been on two medications an SSRI Sertraline AKA: Zoloft and an atypical antidepressant Bupropion AKA: Wellburtin which actually is a DNRI
My personal experience with these medications has not been all that stellar.
When I was on Zoloft I had a major complication, I had become irritable, agitated, annoyed, my senses were heightened beyond normal and I was very snippy, more sensitive and I would snap at the smallest things. I went against doctor's wishes and went cold turkey because I nearly acted upon my agitation. I was never like that.
The Wellbutrin gave me not only headaches, but migraines. These happened daily and got progressively worse until they all stuck together and I had run out of pain killers to deal with the intense headaches. (I've broken my arm and didn't cry, so that gives you an idea of how much it hurt.) I also had the lovely partners to go with the severe pain which you're probably familiar with if you've broken a limb and have decent nerves.
I am not a doctor, I am a peer.
I am in no way saying you should or should not start or continue treatment.
It's a life choice and I feel that you should do what you feel will truly make you happy. Nothing will ever, ever replace a healthy diet and exercise; do this often and you will feel yourself get better. What has worked for me in the past with no bad side effects has been diet, exercise and Vitamin D supplements with fish oil! No joke!
I wish you luck on your quest to happiness, just don't forget that there may be many different pills that you need to try until you're stable. Don't give up! I believe in you!
