Can a therapist fill out the documents needed by Amazon for an LOA?

I've been working 100 hrs a week to cope with the loss of my dad between two jobs and caved and went on a two day LOA to catch up on sleep. I've decided to use Amazon's free therapy resources in hopes to manage the stress and was wondering, can they help with my LOA? Or am I screwed and the UPT will be deducted at the end of the month
