Ready to cut out pumping sessions...physically, but mentally?

CA2006

We made it to 6 months! This was pretty much my goal. I went back to work at 12 weeks PP and have been pumping 3 times/day at work, once in the morning before work and once before bed to get enough for DD to eat at daycare.  Now that we have made it 6 mo, I don't even knwo where to start.  i had told myself I would drop a pumping session starting today, but am having a hard time doing so (mentally).  I have this number of oz. in my head that I have to have and that is that. I know I need to start offering formula to make this transition real, but I am just having issues with pulling the trigger.

I know that not being tied to the pump and having to account for every oz pumped (or not pumped) is going to help me.  I also know (from the past) that my supply will start to dwindle once I start cutting sessions.  I am ready, but not ready to end BFing.

I guess I just need to vent or get some perspective.  Anyone else go through this?
