I think it's just the opposite problem. I simply don't know what to spend money on. I feel like I spend a lot of money, but somehow everyone is in deeper debt than I am. I just don't want to have all those expensive things. I grew up living out of a duffel bag and lost everything I owned in that multiple times in my life. I just don't want anything.
Buying furniture for the first time was the most stressful thing I ever went through. When I bought my first bed, I just laid on a bed in the shop and just stayed there having a mental breakdown. I walked out nearly in tears and slept on my floor for a full week before I finally called and ordered the bed. It was $700 and felt like I took a nose dive off a cliff.
The biggest effect is my appetite. No one understands why I'm so underweight. If you ever go a week without eating, believe me, your desire to eat food goes out the window. Those first bites of food makes you incredibly ill. I eat everyday now, but three meals is overkill.
