Hey, I totally get what you mean
Ive only been experiencing this for about 7 weeks now but its pretty fucking unbearable at this point. I felt like I was coexisting with it pretty well for the first 4 weeks. The symptoms were just "in the background" as you said. I remember even telling myself that I could tolerate this for years. Thats how on top of it I was. But yet, even during that period of coexistince, it still got worse. It just kept getting consistently worse now i cant even concentrate on anything. At this point i dont understand how I can just accept this. Part of me finds it hard to believe the root cause is anxiety. I definitely contributes to it, along wirh stress. But it just cant be the main cause. It shouldn'tve gotten this bad this quickly.
When it comes to accepting though. I feel like the brain just naturally will do that overtime. Time is your best friend here. I hate the idea of missing out on life, but if you dont allow yourself to accept it, your only gonna be missing out longer. Just take it day by day, allow yourself to feel accomplished to getting through just one day.
