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?


Is my hair addicted to dandruff shampoos?

I have dandruff that responds well to over-the-counter shampoo. Ergo, I have been using the stuff almost exclusively for ten years. No brand in particular, sometimes zinc pyrithione (the blue stuff!), sometimes coal tar (the smelly brown stuff!). Anytime I switch to non-dandruff shampoo for like three to four days straight, I get my dandruff back. I worry that I might be addicted to dandruff shampoo. Should I worry?


Should I come out as transgender?

I want to become a male but I'm trapped in a female's body. I recently saw "Boys Don't Cry" and everything Teena felt I felt. Becoming a male would make me truly happy but I'm hopeless and desperate for a first step to take. I only cross dress in privacy and around my close confidants. My mother would die if she found out. Lately I have been feeling suicidal over my complete and dire unhappiness and uneasiness. PLEASE HELP ME!


Is using rubber bands an alternative to self-injury?

In the past I have self-mutilated and recently there has been a lot of added stress to my life. I've heard about wearing a rubber band on your wrist as an alternative. I was just curious are there any downsides to this method, as an example I have been doing this for a week now and I have gotten a bruise on my hand, it probably isn't from me snapping the rubber band but I was just wondering if there is anything I should know about this method? Thanks
