Does depression/anxiety ever suddenly go away?

My depression/anxiety seems to have magically disappeared almost overnight.

I’ve been taking 2 anti-depressants and going to weekly therapy sessions for the last 3 years or so.

I was getting by but still struggling with a lot of my symptoms. Generally feeling emotionally miserable, pessimistic, afraid, etc.

Well, I don’t know how or why but my depression/anxiety has seemingly vanished almost completely.

The things that were bothering me and running around in my mind have just totally lost their sting.

It’s almost a miracle, honestly.

Has this happened to anyone else? Is there any explanation as to why NOW after so much suffering these issues would go away like this?
