You are doing a million things - finishing your projects, training the new grad student(s), looking for a job, maybe teaching..!
You are not about to lose your mind. You have lost it a while ago.
Fighting with LaTeX cannot be your problem right now.
I more than understand. So, I share in this post my LaTeX thesis template for you to grab and start using.
See how the left panel shows the files involved in the project.
Overleaf gallery of templates
Here is my template:
The link above will take you to where my thesis Overleaf project is published.
You can either grab the files and get started on your thesis on Overleaf by clicking on OPEN AS TEMPLATE
For the latter, you can download the files from Overleaf as a zip file by clicking on OPEN AS TEMPLATE --> DOWNLOAD AS ZIP (bottom left of page)
You do NOT need to have used Overleaf before to access the template files for FREE.
The zip file will be around 20 MB.
