I feel like my anxiety has been through the roof ever since I got pregnant. Like I'm in baby protection mode 24/7. Husband decided he was going to take a solo vacation and leave me home alone for 3 nights. Last time I had to stay home alone I didn't get any sleep because every little bump and noise I heard had me wide eyed and on edge all night. 😔 I have no idea how to fix this.
