OP is this your first smartphone? When I moved from a Motorola to the first iPhone in 2007, it was a very exciting experience. I did wake up in the middle of the night to check my shipping order. The possibilities seemed endless compared to my previous phone. I knew it was going to change my life.
If you are literally losing sleep over a nominal upgrade, then yes you should probably reflect on life's priorities. Perhaps volunteer, exercise, find a hobby (outside of buying iphones) or find a mate and procreate? These can do wonders for clearing your mind from the frivolous things in life.
