Returning to school Spring...next week. Terrified

[ender5803]

I haven’t been back to school in almost 30 years.  During that those years I took classes whenever I could (military and the military spouse).  Last month I started consolidating all my previous schools and training.  To my surprise I had 172 credit. So UMPI requires me to take 10 or 30 hours. Jessica say that is all I need too. I selected UMPI BLS Management because I have a career that only requires a degree now for promotion/raise potential. I do have crippling depression at time that requires  treatment. I am so terrified because I struggle I have these 10 classes and limited resources. I work 80+ hours a week with an  added hour to and from work everyday day 10 hours are unavailable. I am in project management and business currently so the material should be easier for me but I struggle writing papers.
How do you all do it? What is the best way to get through modules quickly?  
Is there anyway to know what I need to begin working on ahead of time for these classes?
My first 4 are:
What can I expect from each with the new brightspace? Most reviews have been under old system that I could find. How many papers and what is the final like?
Bus 141 Intro Project Mgmt/MS Projects
BUS 260 Leadership
BUS 321 Human Resource Management
BUS 415 Operations Mmanagement
The rest will probably be political science classes to fill the remaining requirements.
