A wise person once said, once you understand that things are not yours to begin with, you will find peace. I for one had lost my wallet with very valuable things inside and got it back few hours later. The circumstances of that happening was very low though. I was totally unattached to my wallet although losing it will put me through a lot of hassle. Be unattached to the lost money. Attachment is what causing you this much pain and anxiety. Try doing activities and things to distract yourself from thinking about the money. If something makes me unhappy, I usually go watch a movie or show. Calm down and everything will be alright :)
