You know, I feel the same way. I have never been diagnosed with anything, but anytime I'm really depressed or just feeling down, this ambient/electro stuff really helps me so much. Really soothes the racing mind.
I am not anxious anymore. I used to very on edge about a lot of things, and that has finally vanished completely. This is probably due to many things, but what Paul says to the Philippians often comes to mind, and really rings true: "Do not be anxious about anything, but in every situation, by prayer and petition, with thanksgiving, present your requests to God. And the peace of God, which transcends all understanding, will guard your hearts and your minds in Christ Jesus."
I had no idea this site existed 20 years ago (but my brother & sister and I have found a number of tracks in our mp3 library from the late 90's that originated from OC Remix, so I guess it really has had an impact on me for that long!) But I have been listening to this collection since 2016, and am so happy for this place. Now I'm totally going through and recreating the playlist from @LuckyXIII (are there more than just the 52 tracks pictured in your post above?)
