I can already feel the anxiety rising in My life....I can't make this shit up!

First of all, I’m freaking exhausted! I’m not sleeping at night, so I’m exhausted all day, but by the time I get to bed, I can’t fucking sleep. Thanks PTSD!
Second of all, Brian and I have started the process on attempting to buy a house. He’s talking with a mortgage broker tomorrow morning. I can already feel my anxiety rising. Our lease ends in December and we would like to get into our own place before 12/1. I don’t mind moving thanksgiving weekend if we have to. We moved into this house on 12/15/15. We busted ass to get moved in, unpacked, and decorated for Christmas. Cam was 7 at the time and still believed in Santa so it was uber important to be ready! We also had a housewarming/NYE party. Crazy! I would very much like to not have to rush like that again.
I’ve never purchased a house before, he has, and unfortunately I do not qualify for a VA loan as of yet. My score isn’t high enough and I’ve been working very hard for a year to get it up. It seems to have plateaued at just below the minimum required score. Super frustrating! We’re going to see what all of our options are.
Absolute worst case scenario is we end up moving in with my parents for a while. The worst part about that is they only have a very small 2BR 1Bath house. It’s the perfect retirement home for them though. They don’t need the three of us, a pit bull, 3 cats, 2 birds and 1 fish taking over the place.
I know this is going to be a long arduous process. I just hope my nerves can take it! All positive vibes are appreciated!
