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.


Why was my first time so painful?

1) I have never had sex, but I have tried now twice with my boyfriend, and it has been incredibly painful. It felt like there was a barrier inside me, and the second time I bled. I feel like I am relaxed, and my boyfriend is very gentle and slow, but it still really hurts — more than I think it should. I am able to use tampons — I'm not that small — but I don't know what the problem is. Is it supposed to hurt this much? Could there be something wrong?

2) I'm a virgin, and the first time my boyfriend inserted his fingers in my vagina, it hurt a lot, and I got sore down there. I didn't reach an orgasm, but faked it so he would stop. I didn't enjoy it at all and I was wondering... is this going to happen when I have sex? Is it going to be as disappointing?


What can I do if I'm experiencing an aversion to sex with my long-term partner?

I've been with my boyfriend for just over 4 years. Our sex life has always been the strong thread in our relationship, even when we've had trouble in other areas. We both feel we are the best sexual matches we've ever had. But over the past 8 months things have slowly degraded on my end. He is still as excited as ever, but I just don't feel like it. When we try, I actually feel physically protective, as if blocking my body from a stranger, especially my breasts. It's like a physical compulsion to protect, but neither of us have a history of abuse in our relationship or outside of it, and his approach is loving and open. When he's clothed and we're not about to have sex I love holding him, being held by him, standing next to him, touching him, etc. I'm not physically repulsed by his body: I recognize that he's a ridiculously attractive man! I had some advice that I shouldn't force myself to have sex if I don't want to, but I've also heard the opposite: that I should stop thinking and just push through my body's shutdown. Most of the times when I do force myself I end up enjoying it, but that doesn't take away this "repulsion" feeling at the start. The worst thing is that he feels rejected and dissatisfied and keeps asking what he can do to turn me on. What to do?
