I get this way too! Honestly, I feel like I am just overwhelmed from being anxious about OTHER things, so little decisions become very difficult. I've been pretty stressed from wedding planning on top of my career (which is still relatively new for me, so I am still learning). I've had to make so many decisions and it boggles my mind. I have started just saying "Okay, just do this!" and not really caring because it makes my mind spin to have to think about it and actually choose. Then I get migraines or headaches if I think too hard. Do you all feel like you have a lot on your mind? It can be anxiety related due to a lot going on, situational anxiety, or just stress in general! I know some people who seem pretty calm and still get stressed about decision-making. I tend to get a little bit obsessive about certain things. You mentioned shopping- If there is something I want and a store runs out of it, I will literally spend hours searching online for a replacement item! It's crazy and I wish I didn't do it, but it almost consumes me. I am working on getting over it by making little changes gradually, but it's tough. My old counselor thought it could be OCD-related, since I have some other OCD symptoms. Luckily they aren't too severe where they are interfering with my life, so I choose to work on it on my own! It's my anxiety I went to the doctor for help for!
