Hello Martina,
You have good responses here. Only you know how it makes you feel to think about this issue. Which is more stressful? Thinking about working or thinking about the debt?
That may sound simplistic but when it comes down to it they are the two issues you are facing at the moment. As Echoes said if you are working with a therapist you could ask about working through this, and knowing your issues clearly now you may be able to work around them
But you could also do tax returns from home as sanity has suggested; I hope you are able to decide,
Rhiannon
