i am sorry you are having such a rubbish day CiQ :( I just looked up on the net about trazadone because i'd not heard of it and it appears to react with fluoxetine. Maybe worth checking with your GP about, although im sure they have taking this into consideration. (it doesn't say what the interaction is)
You know it is really ok to take yourself off to bed, it might help to get some rest, could you concentrate on a book do you think? I find sudoku is quite distracting.
When i lost my dad my DP wasn't especially supportive but really, what could he say? nothing - my dad was ill for a long time and as cliche as it sounds, there was a great deal of relief when he finally passed away. If your DH's dad is quite poorly, it may be that he feels the same? I was expecting some sort of devestating greif but it never really came and i adored my dad. Everyone processes grieft differently i guess, so don't feel that you need to be the crutch for your DH, only he can really process those feelings and children are more resilient than we give them credit for.
I broke my dry january today and treated myself to a gin and tonic earlier on while dd was at her tutor, dp and i usually do our aldi shop but both our brains were cabbage by this time so it was nice to sit and relax for half an hour, we are havin KFC for dinner 
Have a doctors appointment tomorrow to talk about the dosage of escitalopram. Not quite sure what to do, i think i want to up the dose.
