1. You remind yourself that at one point (even if it was back in high school) you weren't married and didn't even have any sex partner other than yourself...and that even that was better than what you've got right now.
2. With that in mind, you go back to whatever satisfied you back then. After all, you WERE satisfied back then, because it was your only choice, and you not only survived, but you enjoyed it. It's only the reflection on what you EXPECTED but are GIVING UP at THIS point in your life, that stops you from at least enjoying what you had then---so try not to dwell on that. (Not easy, I know, I know, but it does help if you succeed in avoiding it).
3. You DO treat yourself to "bubblebaths." (Sorry...go ahead and ridicule...but they do help). Just be sure to supplement that bubblebath with a handheld massaging showerhead. Apply wherever and however liberally needed.
The point is, the fact that you are being deprived of the steaks to which you are rightfully entitled may not be something you can do anything about. But you still CAN have some VERY good hamburgers. So make the fanciest hamburgers you can afford the ingredients for - and when those pangs of longing and regret come along, shove them aside and don't let them stop you from enjoying the hamburgers. Remember: you survived without steaks back when you couldn't afford them....and you were still happy and well fed...so let those hamburgers satisfy your appetite today. Think about what IS still on the table rather than what ISN'T.
