Doubts and Annoyance Nonstop 😳

Is anybody else extremely annoyed by pretty much everything? Especially my partner drives me nuts... Before we got pregnant I was so happy and sure of our relationship. But now I'm questioning everything. I love him but will we be strong enough to carry the weight of being self employed, loosing one income, servicing the mortgage and all the stresses around having a baby etc? I feel bad for having all those thoughts...
