babygirl, you gotta clear out your lungs... Ganja is coating your reseratory system the same way it does your pipe.. Imagine if you didnt clean your pipe after a 16year smokefest?? it would be clogged with resin... my suggestion:
Since you don't know for sure what the main source is, your best bet is to clean out your pipes.. start with a supplement and add some broccoli and keep coughing out all that ****..
from a smoker to a smoker, vap is the only way to go!
be smart and stay strong.
I sympathize with the misery you have experienced this past year. Vomiting every morning could be secondary to stress but it is equally likely that there is a physical cause or possibly a body response to one of your medications.
Chest pain is not a symptom of COPD but is a symptom of a variety of other disease states. Shortness of breath is a symptom of COPD but also a symptom of a lot of other lung diseases, a number of which, most notably asthma, would not show-up on a chest X-ray.
I gather from your description that you are in dire straits, emotionally and/or physically. You deserve better. The best advice I can give is that you seek consultation with an Internal Medicine (IM) Specialist (a diagnostician), one who will give your problem and you the time and interest that will be required to sort-out your quite complex situation. Most IM doctors will schedule 30-45 minutes for a first visit and that is what you should seek.
Good luck
