I've always had crazy dreams. Usually I'm trying to get away from someone/something or I am trying to find someone/something. It's a super common theme for me. I actually quite enjoy them once I've woken up and realized it was another dream.

And what makes you think you're failing? I doubt that you are. Maybe you're a bit stuck but you won't always stay stuck. And unless you're already 90 years old please don't wish to not live more than another 20 years! (Wow how useless is my advice?!?!)

Have you talked to your doctor about the meds? Hopefully they start helping out soon, but maybe it's just not the right dose or maybe just not the best medication for you?
