The number one piece of advice that I can give is see a doctor. Not a psychologist or psychiatrist - just a medical doctor. Tell them your main symptoms (low energy, difficulty focusing, panic attacks) and have them run some tests. Those types of problems can have physical, medical causes (including conditions involving the thyroid or blood sugar - hyperthyroidism & hypoglycemia). If a medical problem is a big part of what's happening, you need to get it taken care of.
If you're having trouble getting yourself to the doctor, then you need to find a way to do it. Can you ask someone for help? Would a family member help you set up a doctor's appointment and help get you there? A friend? You might even be able to find someone on Less Wrong who lives near you and could help.
My second and third suggestions would be to find a friend or family member who can give you more support and help (talking about your issues, driving you to appointments, etc.) and to start seeing a therapist again (and find a good one - someone who uses cognitive-behavioral therapy).
This is technically a good idea. What counts as "my main symptoms", though? The ones that make life most difficult? The ones that occur most often? The most visible ones to others? To me?
We've had these for a year, I'm sure we all know what to do by now.
