my mom died and left me with a disabled brother to care for, 7 cats to find homes for, and two houses full of stuff to clean out and sell. i have had severe anxiety since the day she died 7 months ago, including trembling, heart palpitations, insomnia and weight loss. strangely i have had binocular double vision since then as well, more so at long distances, that i can alleviate by covering one eye. i think its getting worse. could my anxiety be the cause?
