My father has schizophrenia. My great grandmother was manic-depressive. What are the genetic risks of my child being schizophrenic if I have one? Are there any tests that can be done either before becoming pregnant or prenatally to determine probability? Has a gene been found linked to schizophrenia?

I really want to try pot because I am SICK of being uptight and careful all the time. I have been depressed and anxious for several years and I just want to feel SOMETHING different. But I've had a couple of panic attacks (both related to medication) and they were the most frightening things I've ever experienced. I'm scared that pot would do the same thing to me. What do you think? I know you can't encourage me to smoke pot but I would very much appreciate an honest answer, which I know you always give. (I know that smoking pot is not the best thing to do when you have depression and anxiety, but it would only be once, and I would be with friends. By the way, I'm not currently on medication as I find it useless. But I'm not trying to self-medicate. I just want to remember what it's like to experience an emotion that is not depression or anxiety). Thank you very much.

I'm a first year college student. Since the holidays I started experiencing a very strong horrible feeling; so horrible I preferred to die than to keep on feeling it (the suicidal thoughts come and go still, but it's not as strong as in the beginning). It's very puzzling though because I don't have a reason to feel like this, not one that I know of at least.

I thought of going to a psychologist, or psychiatrist, but I don't have money to do so, and I thought that maybe I should try curing myself first. Is there any way to try to fight depression by myself? Also, if I don't have a reason to feel depressed, what reasons could there be for what's happening to me? I read in other things you wrote to people that depression may be also caused by chemical imbalances in the brain. How do I know if that's happening to me?
