Hi there,

It does sound like a lot of what you're saying could indicate anxiety, especially since you're having irritable moods and a lot on your mind. Anxiety can manifest as physical symptoms such as heart palpitations as your body and mind are connected. It's possible that anxiety is part of the problem here, but the best thing you can do if you're unsure or worried, is speak to a doctor. Especially since you're having heart palpitations, it's worthwhile just getting yourself checked over to ensure it's nothing serious, just as the posts above have said. A doctor might also be able to help you with finding tools which will help anxiety if that is the cause too, such as breathing exercises, grounding techniques and perhaps medication if it's considered helpful.
