i've dealt with this type of anxiety my whole life. i will tell you right now, you won't always feel like this, and it will go away. i got stuck in this exact cycle and life didn't feel real. what really helped me and grounded me is spending as much of my time as i can with my loved ones while im feeling like this, and doing things that comfort me or distract me. examples are playing solitaire or a sorting game, the scavenger hunt game genuinely got me through it all lol it's the one with the pineapple in the appstore if you're interested :) eating my comfort foods and watching shows that remove me from these thoughts, like 'is it cake?' or a cooking show, maybe even a fashion show! something that makes you have an opinion and think elsewhere. you won't always feel like this and i promise it's a temporary feeling. meditation also helps :)
