How exhausted is "normal" exhaustion?

[mamababy1955555]

I'm 33 weeks pregnant with number 2. I have a 3 year old and gestational diabetes, so I'm on a very restricted diet. I feel EXHAUSTED. I feel like I can't cope with my kid I'm so knackered. Is this normal?!?! I'm so worried something must be wrong with me but I've had every blood test under the sun and apparently I'm fine, baby is thriving... I can't reconcile this with how I feel.

I feel like this at 30 weeks with my 16 month old! I think it's all the extra running around we have to do after our kids! Absolutely cream crackered!
