Anxiety has returned

Hello all,

Ive been having anxiety on and off since a kid, but each bout having many years in between each episode. Usually I am a non anxious person who never has any feelings of worry during their day, but when anxiety creeps out of nowhere it will last for weeks to months and I tend to dwell on the issue making it worse. I always worry of what may be causing it which tends to not solve anything but prolong the anxiety even more. I dont have panic attacks but just a feeling of anxiousness throughout the day and feeling lost in my thoughts. When I feel like this, my thoughts/imagination always seem to work against me when I try to be logical. I seem unable to bring myself back to center. I am able to get sleep most nights but sometimes become afraid of the many thoughts that drift through my mind as I tend to notice my thoughts more when Im anxious. I am still working a full time job,getting decent sleep, eating when I can, and still making an attempt to not let it ruin my routine. Ive beat this before, returning to my normal self and anxiety becoming a thought in the past which gives me hope. If anyone has any feedback, it would be greatly appreciated!
