So frustrated with everything

I’m 30 weeks and a day and I literally don’t know how I’m going to make it ten more weeks. I’m so tired of being tired and feeling huge and not being able to enjoy walking outside because it’s so hot in Texas and ahhh. I’m just going insane being inside and having nothing to do. :( I used to go to the gym really regularly and haven’t had any drive to go since being pregnant and it’s just all been so hard on my mind and body. I just want to hold my sweet baby already and just go on adventures and be done with pregnancy. :(
