I’m really struggling

With the pandemic and me being pregnant my dog and I have gained a SERIOUS connection. So much so that it’s basically unhealthy for him and me. I hate leaving the house even if it’s only for a minute because I hate being apart from him and he is the same way. We’re taking a trip to my grandparents and it almost makes me nauseous thinking about it I’m struggling to even get excited about this trip because I hate being apart from my dog. I know once I get out there I’ll be excited and it enjoy but I also know I’ll be sad a lot of the time to because I’ll miss him so much. I know it sounds ridiculous but i cant help it. Can anyone offer advice so I can get through this trip!
