I was just given my first phalaenopsis orchid last week as a gift. It is beautiful and honestly I'm terrified! I've heard that orchids are difficult to grow. I've also heard they're easy to grow. Every website I visit seems to give different advice. The reason I'm terrified is that I've killed almost every plant I've ever owned. There are a few cactus plants struggling to survive on my back porch but nothing else has been able to overcome my black thumb. You all seem to love orchids so I'd really appreciate your help.
If possible, I want to keep my phal in my office because it will be easier for me to focus on giving it proper care than if I take it home. Also, I think my cat would thoroughly enjoy smacking it around. Yikes! My office is a pretty consisent 68 degrees F, but has no windows. There are flourescent lights in the ceiling and also about 2 feet above one side of my desk. Do you think the orchid would do well in this environment? I've included some photos but they were taken with my cell phone so may not be the best quality.
From the various orchid care websites I've recently visited, I know I should water my phal about once a week taking care not to wet the leaves and use orchid fertilizer sparingly once a month. It is currently potted in what appears to be moist soil with mossy wood bark on top. I really don't want to be reponsible for the death of this gorgeous orchid. Please help

Thanks.
