Dear Tiggerbow~
I'd like to welcome you here to the Forum. It takes a fair bit of courage -or desperation -or both to reach out, and it is sad to hear both you and you husband are going though such hard times.
You autoimmune condition and you husband's work are the sort of things you can't directly influence, life gives some a very hard time and no easy way out. What one can do is try to cope better, and here there is some good news.
For a start your depression and anxiety was controlled in the past with meds and counseling. That potential to improve is still inside you, and is starting to emerge now you have seen GP and a councilor again. For a while it helped. That's great!
I notice you did not mention meds this time around , did you discuss them with your doctor?
Another good thing is your strength. You work full time and did finish your degree, both impressive achievements for someone who had your conditions.
I guess the idea is for those visits to GP and councilor to have a longer effect, and here there are techniques that do help. I too have had bouts of depression and an ongoing anxiety condition and have found that my own actions as well as the doctor's can help.
Beyond Blue has an awful lot to say on both conditions, however I'd suggest you check out firstly
https://www.beyondblue.org.au/the-facts/anxiety/treatments-for-anxiety/anxiety-management-strategies
which is general and has ideas to help plus also here in the Forum a thread called:
https://www.beyondblue.org.au/get-support/online-forums/anxiety/self-help-tips-for-managing-anxiety
which is very long -but I've waded though it several times, always picking up new ideas others have successfully tried. It all helps.
Come to that maybe your husband might have a look for himself, the waiting will be very hard when away from work
I try to have a time each day I can look forward to, something completely unrelated to ordinary life, for me books and old movies, different of course for others. What do you think might help you take your mind out of the present each day -anything from exercise to games?
Please remember that you really are facing hard knocks, anyone would be hard-pressed to cope, but you have coped before and I have no doubt you will again.
Also try the free smartphone app Smiling Mind, it really does break that cycle of thoughts going around and around. I find it essential at times, even the 2 minute intro
I do hope you come back and talk more, say what works, how things are
