nothing special

I haven't felt this bad in quite some time.  I've been taking Talolmil for the last two and a half months, and up untill Sunday I haven't felt so good in my life.  And then suddenly everything just went from excellent to hell.  I feel like I can't go on like this.  I feel useless and nothing I do is ever good enough for anyone.  Even the nanny is taking my son out of my hands because she doesn't think I know what I'm doing.  I just want to disappear and I know no-one will miss me.  It's not like I play a role that is of any kind of importance to anyone.  Even at work they can replace me with someone who I'm sure can do a much better job than me.  I sincerely can't see the point of my existence....
