Historically, i've had very tricky bouts of anxiety. My earliest memories of struggling were panic attacks relating to a fear of mortality as a child.
Recent years I seem to have had really bad flare ups around specific, diffuse issues; but i'm turning 40 in 6 months and all those issues seem to have built to send me back to my childhood, and I feel just completely overwhelmed by waves of existential dread. Just a real sinking feeling in my stomach, heart palpitations, panic rising. It's really quite awful, and I hope it'll pass as it's utterly unbearable.
Sorry, I appreciate that isnt as serious as the stuff in this thread but I just need to get it off my chest as it's really hard to talk to someone about it and be taken seriously. Everyone gets old, I know. I need to get over it, I know. But that doesn't make it feel any less awful right now.
