How can I start practicing meditation, yoga, or tai-chi?

Recently I've been thinking a lot about ways to relieve my stress and other mental problems such as OCD and ADD and I have been hearing that meditation, yoga, tai-chi, etc. can possilby help with these problems that I have been suffering with all my life, but I am very confused as to which one would be the best for me.

Also, if I find out which one would work the best for me, how would I go about finding someone that could teach me these things? Or is a book a good way to go? If a book is a good way to go would you suggest one of those "The Complete Idiot's Guide to..." books?


Are there health concerns associated with consuming Sucralose (Splenda)?

1) What are your thoughts regarding the use of Splenda as a sugar substitute? I have heard that the body is not able to metabolize this and that it is excreted through the urine. Do you have any current research on Splenda and the side effects? I realize it is a relatively new product. Thank you!

2) I searched the archives and found no information on Splenda or sucralose. Lately, it seems like Splenda is gaining popularity in the crowded sugar-substitute category. It seems too good to be true — measures cup for cup like sugar, you can bake with it and mix it into drinks, and it is made from sugar so it really tastes like sugar. My two questions are... is this a safe product, or are there some disadvantages with the product? And secondly, if it is very safe and versatile, why aren't more companies using it now?


Do I have obsessive-compulsive disorder (OCD)?

1) I think I might have OCD. I worry about it a lot and I want to go to a doctor, but I am too afraid. Can you please tell me the symptoms of OCD. Thank you.

2) I think I might have OCD. Since I was about 12 or 13, I started thinking really strange thoughts. I always felt like there were eyes watching me. I know its irrational to think such a thing, and I know there aren't any, but I get this weird feeling there are. I have to cover my windows in dark colored papers and check for any holes in them regularly, so there isn't the tiniest hole for someone to peek through. I have shades as well, but I never feel like they're enough. I also have to regularly make sure my windows are locked, sometimes I'll lock and relock them a couple times until it feels like the lock worked. The same with my bedroom door, I will not sleep at night if my door is unlocked, and sometimes I relock it more than once, or even reclose my door more than once. It doesn't always feel like it properly shut the first time. I also have to turn any faces away from me. My stuffed animals can't look in my direction, and I wont hang pictures up in my room if it feels like it has eyes on it. I'm not scared of eyes necessarily, I know some people with beautiful eyes. I just can't take them staring at me. I also know they wont hurt me, either, but it feels as if somehow they will. I don't know how.

I'm really feeling like I might be going crazy. I'm stressed out beyond belief! Should I bring it up with my doctor? Should I get a therapist? Could this be OCD?
