So my anxiety has been through the roof for the past year and hasn't stopped (toxic living situation, zero close friends, a relationship that was my only saving grace ended, everything going on in the country, etc.). But usually my anxiety is in the form of tightness in my chest &amp; difficulty breathing, which I can get through by focusing on my breath and deep inhales/exhales. But the past few weeks I've been feeling this prolonged heaviness in my chest and getting anxious at the slightest triggers (and certainly everything happening in the country rn is making it worse). but I don't know what to do about it because I've tried focusing on my breathing but it doesn't help at all. I've tried researching it but it's not that I'm short of breath, just this overwhelming heaviness (physically and mentally) that usually lasts from the middle of the day and through the night until I finally go to sleep (it's also accompanied by never-ending thoughts since I'm currently trying to find a job on top of everything else I'm dealing with). Can someone please explain to me what this is? Have you experienced this before? And what do I do about it?
