i really agree with the practical advice you ve already gotten from the responses here yoda. all i can add is that it might help to tell your T exactly what you have posted here and to ask him/her if s/he can help you look for a case manager or organise to get someone in to help clear the house or motivate you to clean it a bit.
you can get through this. sounds like you are collapsing after going through such a traumatic time. you need as much help as possible but you can come through this and life can only get better from here. your difficulties are mental now and you re not threatened physically any more. these difficulties may be harder to identify and 'see' but, with help, you cant take back control here.
good luck. keep coming back here and posting.
good luck. keep taking control of each little bit you can as you can.
