Tiny fish - there are many people who will "hold your hand" for as long as you like. The support on this MH thread is incredible. Most of us have/are suffering from some kind of MH illness and so understand each other.
I don't understand why the GP who diagnosed youwith depression and anxiety could not prescribe for you because you were a temporary patient. I am not a medic but have suffered 2 major episodes of severe depression, the latest one last Easter and my recovery fluctuates without any known triggers.
I can identify with everything you say, the not wanting to get out of bed (when we are depressed we want to withdraw) feeling lightheaded (which is possibly a symptom of anxiety) as I had that too, prolonged bouts of crying etc are all classic symptoms of severe depression. I think the fact that you are seeing things as if on a TV screen is called de-personalisation and is another symptom of severe depression. Your suicidal thoughts are also a symptom. I too have felt it would be better if I wasn't here, though with me if was (and stillis at times) the canal rather than a car.
Look tinyfish - I am going to be very prescriptive.
You are ill and you are in no fit state to be working, and driving is dangerous for you and others. You need to get to a GP ASAP and tell him/her all your symptoms (they have a check list anyway) or you can write them down as bullet points. You absolutely need to be signed off work and to get medication. You need to stay in bed late because when we are depressed we want to withdraw and if your bed feels safe, then stay there, but not all day. You must get up and shower and a short walk in the fresh air is always helpful. You need time to rest and relax and have the pressure of work taken off you.
I honestly think you are heading for a severe depression unless you get some help now. Clearly your partner going abroad has heightened your anxiety and that is not surprising. Do you have any RL family or friends nearby. What about work colleagues - is there anyone you feel close enough to so that you can phone when you feel scared.
PLEASE phone for a GP appt and say it is urgent as I honestly think that is your best course of action.
Come back and tell us how you got on. And you must get signed off work.
Sorry to sound so bossy but I know how difficult it is to get help for yourself because depression is a very deceitful illness and makes us think it is our fault and we're not worthy of anyone helping us etc etc etc. Please believe me that is the depression "talking" and one of the hardest things about this horrid illness.
Sending warm wishes and take care NN xx
