Hi Timothy.

Scary stuff, especially for someone so young. I'm probably close to your grandmothers age and when my anxiety kicks up and I get those odd pains I freak out a little too. But I know it's just anxiety and I ignore it.

The first thing I'm going to tell you is really really important. DO NOT GOOGLE SYMPTOMS, EVER!!!!! All that's going to get you is into a complete panic and that's not what you want.

Glad the medicine is starting to work, it's going to take a couple more weeks or so to really kick in, so you can look forward to that.

As for your diet, eat sensibly. At 17 now is a good time to get into good eating habits. Fruits vegetables, good protein, that the best way to go. Ease up on the take away, or anything that is prepackaged. Ease up on too much sugar, that includes soda and sweets.

Don't worry so much about cholesterol, your body is still growing and it needs the cholesterol to make hormones and stuff.

Last but not least, know that you are going to be alright, just carry on with your days and everything will get better.

Cheers!
