Dealing with stress and anxiety palpitations

Lately, I have been dealing with some stress and anxiety that is resulting in palpitations. It’s tough to deal with this on my own and I’m looking for advice from people who’ve faced similar issues. I’ve been trying deep breathing exercises, gentle stretching, and taking breaks throughout the day but nothing seems to be helping. If anyone has any tips to help me reduce my stress level and cope with anxiety palpitations then please let me know!
