Cannot sleep, I'm too excited 😩

I seriously get so tired throughout the day and especially in the evening leading up to bed time, but I can't nap when it's light outside and when it's night and I go to go to bed it's like the moment I'm in bed I'm wide awake, thinking, thinking, thinking about this baby and how close we are! I've even been up from 4am the last few mornings because I can't get back to sleep after that 4am toilet trip because the baby is kicking and it gets me excited lol. I feel like I'm gonna go mad with all this waiting around!!!!
