Welcome to HW and our A/P Forum :)
You are going through a lot lately and it seems to be self induced with the fear of dying. This is called Anticipatory Anxiety and there are a lot of us here that suffer or have suffered from it. Hopefully after having an EKG, your mind should be at rest, because if there was anything dangerous happening, it would have showed. As for the high blood pressure meds, I'm sure that all of the stress you've been under has contributed to your blood pressure rising, but you must keep in mind that a person's BP along with Pulse will vary several times everyday. So just have the clinic doctor keep an eye on it and try not to worry.
We have some free resources here that will help you out :) On the main page of this forum, go to the top and you will see a thread labled Anxiety - Panic Resources. There you will find links to free online CBT (therapy) and also really wonderful breathing/relaxation exercises. The CBT will help you rationalize your anticipatory anxiety and the others are just great to help keep calm. And, please do stick with us here for the great peer support, because that is an important part of your recovery.
Take care now and check out those links :)
