Spaced out

The last two weeks at work have been hell and with no support at home and no one to talk to I don't know what to do anymore. I am on the verge of tears all the time. I'm not sure how much more I can take. I feel like no one cares anymore but I keep on smiling. Even the wonderful weather we have been having hasn't managed to make me feel good inside. In fact I am sitting in the garden now with tears rolling down my face. I managed to snatch a short chat with a good friend about the situation on Friday night but that wasn't really enough. My boss two up has texted me saying he is wondering how all of this (work issues with London 2012) is impacting me and asked me to call him the weekend. I plan to today, but how much to I tell him ? How honest can I be without sounding female and weak and risking my job ? I always thoughts was a strong person and on the whole I think I am but I need someone who can be there for me during my weak moments. I know the girls love me but now is the time in their lives they are just growing into their own relationships and I need to be strong and there for them. It's not fair for me to burden them with how I feel. Yesterday when going about getting things ready for my daughters birthday today and out for a meal with her I felt very odd. Almost like I was not really there. Just looking at myself doing these things with no feeling or purpose. I really do think I may be seeing glimpses of real clinical depression. Now comes the time to admit I have been having some councelling but that is finished and I have to apply for more. It was helping but the new times have to be between 9 and 5 and with work I can't do that. What should I do ? It's been 18 months now :-( I don't know what I need for closure and to move on maybe I never will. And the manipulating ***** has what she wants and though my husband says he cares I'm not sure he really does anymore - he is no better than her. How can humans be so horrible to each other for their own selfish purposes.
