Trying to balance work, life, family, & baby making

just need to vent. I'm losing my shit lately bc my husband & I started ttc a couple months ago...and between my 40 hr/wk fulltime job, which is very stressful.. then my 2nd job (up to 20 hours on the weekends), then balancing my family, & my relationship, & downtime for myself...it's like I have nothing left when it comes to ttc. I want to WANT to have sex & make it fun & enjoyable for the both of us. but lately it's just like it's become a chore & a nuisance & like ONE MORE THING TO DO. I even hate typing that bc I know it's wrong & terrible! I'm more than ready to have a baby with my husband, it's not that...I'm just letting too many "outside factors" affect me (like stress & being tired & overworked) and it's completely taking away from us trying. we got into a big blowout fight the other night bc he wanted to have sex & I was just like dead tired, on the couch, and had NO interest. obviously a big turn off. I feel terrible, and don't want him to feel shut out or like I don't want this. I just need help balancing my damn life right now & focus on my priorities! am I totally alone here or what? :-(
