Hi LR and welcome!
I am sorry to hear of your mom's passing, and the subsequent stress that you have been experiencing lately. I understand that very well, as I am also the type of person, who gets the job done (no matter how difficult) but then falls apart with anxiety symptoms after the fact.
I suspect that is what is going on here...so once you can get in to rule out any other physical possibility...you can confidently start to work on your anxiety management.
There are many options including medication, therapy and self help. The first two would be discussed with your doctor for Rx and/or referral...
...but self help you can get started on right away! In our Resources at the top of the main forum page here you'll find great material that teaches Stress Relieving Exercises and other coping skills such as Meditation, use of Postive Mantras, Mindfulness and more. Practicing these will make a big difference in how you feel. (we have a couple of links specifically on PVC's/palpitations so be sure to check them out!)
As far as our Chat feature....unfortunately it is not very active. However, you can post here as needed, and someone will be here to reach out to you and hopefully give you the reassurance you need during your most challenging times.
We understand, care and support is key...so keep posting.
