Long story short I was diagnosed with anxiety &amp; depression as a pre-teen &amp; was put on medicine for about 5 years until I quit cold turkey not really sure why I guess I felt they weren’t helping , it’s gotten very bad the past few years  &amp; now I noticed that I’ve been spacing out for hours at a time and then “snapping back into reality” I don’t know if I just sit there or if I do anything during the time . How I noticed was I’d look at my phone and the time change would be a huge gap , I guess my question is does anyone know why this is happening to me . And does it seem serious ?
