Hi Charlie,
Sounds like you are surrounded by a lot of depression (I mean with your family, and being a therapist yourself).
You have some great tools to combat the depression. You have your therapist, your books, and your Professors.
Do you have "toys"?
Things you give yourself to make you feel happy.
Take time to enjoy things unrelated to your occupation.
Take vacations, go on weekend trips and stay at a hotel (with pool, sauna, and restaurants).
Make it a point to eat at a different (or favorite) restaurant at lunch time to help break up the day.
Take outside courses in something you have an interest in outside of therapy (swimming lessons,self defense classes, pottery, another language, computers).
Shop for furniture (used or new), and pick out something really nice for yourself. Redecorate a room, or even a special corner to reflect relaxation, or an interest you have.
Build an inside fountain, a bar-b-que, or different lighting and grow plants and trees inside. Try new foods and recipes or take an interest in animals.
Relax, enjoy life, make time for fun and the interests that are inside of you.
Be good to yourself!
Best Wishes,
Colors
