Stressing over non necessities.

So I've been so anxious lately worrying about how I'm going to get a nursery going for my totally oops pregnancy and it's really getting me down i also worry about how in going to afford all the things I need clothes a double stroller I have another child and all. I'm too far in for an abortion I chose to keep and I want to keep my child someone tell me that this stuff is extra and we can be happy and survive without a nursery set etc😢I mean I know it's true but I feel awful with my first planned son we had savings and made him a nice nursery and had more than everything we needed. Now I'm just so tight and stuck and this is all so up in the air im approaching 21 weeks and it seems to be more and more real that the shit is about to hit the fan. I wish I could just stop caring and be happy with what I have.
