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 there a connection between cortisol, depression, and weight loss?

I recently went to my doctor because I've been unable to lose weight. I've been on a successful diet, accompanied with a reasonable exercise plan, but I've seen no real results. A series of tests were run — I've got optimum blood pressure, low cholesterol, and I am not diabetic. But, when my cortisol levels were checked — they were very high. The doctor suspected there was a possibility that I might have Cushings' Syndrome — but another test was run and that came up negative.

I was doing research on the internet, and I found that there was a link between excessive cortisol and depression. I was diagnosed with clinical depression when I was 12 (I am now 21). And I am currently untreated. What is the link between cortisol levels and depression? Are excessive cortisol levels a physical manifestation of depression? Or does an excess of cortisol for some other reason cause depression? Does an excessive amount of cortisol cause weight gain, or in my case prohibit weight loss? And if there is a connection — will treatment for my clinical depression (in the form of prescription pills) help me?

I've been unable to find answers anywhere, or at least a good source to tell me to stop worrying — any help would be appreciated.


How do I talk about ableism without losing friends?

I have an invisible disability and I'm really getting into disabilities activism. Even in liberal circles ableism is still pretty accepted and this upsets me. However, when I try to educate people around me, it sometimes goes awry. I had one friend get upset when I called her out for using the word "retard." Another got upset when I pointed out that her Facebook post of inspirational people with disabilities (that just showed people with disabilities doing normal things) was a little offensive and tried to tell her about "inspiration porn." I get that using the word "retard" is normal as is "inspiration porn." I just don't think it should be.

I know my friends are caring, socially conscious people. I expect people to be a little upset, but ultimately I would also expect them respect the fact that it's really not OK to objectify people with disabilities in the way that inspiration porn and the use of words like "retard" do. What I want to know is how do I point out that people are expressing a harmful social bias, without having them get so upset that they write me off as an over sensitive concern troll?


Is sunscreen necessary for dark skin?

I am African-American, but my skin is not that dark. I was never told that I needed sunscreen and when I worked in a daycare I was told in a very delicate manner that only the paler children needed sunscreen. I've been out in the sun for extended periods of time and was wondering if sunscreen is necessary for someone of my complexion. If so, what strength?


Does being a lightweight drinker have anything to do with my liver?

Does the classification of a "lightweight" with regard to alcohol consumption imply anything about the liver? In particular, is there anything abnormal about feeling tipsy after only one beer (vital stats = 155 lbs., 6 ft.). I know my family has a history of liver problems and I have in the past drank to excess on many occasions. It has never taken much to become inebriated and now it takes even a little less. Should I be worried?


Will starting and stopping the pill increase my risk for cancer?

I have been on the pill for over a year now. Recently, I broke up with my boyfriend of two years. We still see each other, but I have not had sex since we broke up. I don't plan on having sex with anybody else. My question is, if I don't plan on having sex for a long while, should I stop the pill? I am afraid that if I decide to get back on the pill, I will have an increased risk of cancer or something like that. Is this true?


How can I prevent athletic performance anxiety?

I compete in an individual sport. The problem is that on the day of a major competition, I have really bad indigestion. Sometimes, I have to run to the bathroom every half hour for a bowel movement! Besides being annoying, disgusting, and a little embarrassing, this interrupts my competition and adds unneeded stress. Why is this happening and what can I do to prevent it?
