I'm feeling the same way, and when I brought it up to some friends in tech it turned out in our group of 8 I was the least depressed.

The wife of another friend of mine confided in me that AI replacing his work in such a short time has made him depressed to the point she's getting scared he'll hurt himself.

I think we need a support group or something. But I'm too busy burning the candle at both ends trying to "catch the lifeboat" before its too late. So are most other engineers I know.

I'm sorry you're going through this but know not only are you not alone, but you're in the majority of software developers at this point (I think, anecdotally).
