Pregnant again

Ok so I recently found out I’m 6-7 weeks pregnant (were very excited!) and we also have a 9month old baby girl , so my life is already pretty busy and I’m a sahm, but lately I’ve been having trouble excepting the idea I’m going to have to go through all of that again so soon. I know the fact that my fiancé is in Vegas for the weekend doesn’t help((which the trip was planned before we found our& I wanted him to go) but just thinking of everything I’m going to have to miss again is on my mind because I’ll spend another birthday pregnant (oct 14th) idk if I’m just venting but any advice for any moms who had baby’s close in age ? I’m very excited I was just getting comfortable with wanting to go do things I couldn’t do from my 1st pregnancy and being happy when I could go out now since she’s almost 1 but now I have to cut off any plans I had for another year. I needed to start getting out it was helping with my anxiety and depression from losing my brother last year.
