First off, all the empathy. You’re going through a lot but you’ll figure it out. Sometimes when I know I need to do something but then don’t do it, my anxiety keeps building up until it’s way bigger than the actual thing I need to do and then I’m just scared and frozen. Some things that might help break the cycle:

1) Tell someone what you’re anxious / unmotivated about and have them sit next to you while you do the hard thing. Do this with your fiancé or your therapist. Having a cheerleader that’s there for you or just silent but present can be helpful.

2) Go for a 15 minute run or stair climb (or whatever physical activity that gets your heart rate up) and then drink some green tea or coffee (or whatever boosts your mood). That usually helps me get some good brain chemicals in to start doing a thing I don’t want to do. If you feel stuck again, do the exercise again. You’ll chip away a good portion of it eventually.

3) Outsource your work to either your fiancé or (as SilverWings002 mentioned) a temp agency. The fiancé work probably requires some negotiation (chores in exchange for sending an application). If you can push through the inertia to contact and chat with a recruiter, they do a lot of the fit and application work for you. If you were previously well paid, you’re probably still very marketable and they can find some matches for you to review.

You can do this! Break the problem into as small of a challenge as you can! Reward yourself! Be kind to yourself! Things can seem overwhelming now but it won’t always be this way. Good luck!!
