vge, so sorry to come across this recent development, above, 'more drama.'
You have received very sound advice re: the posts following your own - job, gwen, kml ... livenow 'chimed in' (doesn't sound like a keeper to me - & in this condition, he is NOT)
I read that your lawyer's sitch is similar to your own so you 'follow as directed' of course. However, it might still be prudent to 'mentally file' this info. away. You never know, you may need to re visit in future, life is strange that way.
I do echo the sentiments of yourself & the others (let the lawyer do what she has to for you). As for you? You have ONE thing to do & that is to continue to reach out to your (many) support systems during this time of adversity. Keep them alive. Your in laws are a let down . Your h has even more (!)'goodies' on the way for you - although even he doesn't know it yet!!! You have this one thing to do for you - use your support systems to keep your head above water.
Your body is fighting a war with the cancer, your mind is fighting a war b/c of the mlc + all the associated fall out (!) ... ow, in laws etc. Fight - your support is your 'army'.
You are at war vge, so *strategy (below/col.) as in war, is key to win these battles of mind & body. Fight this bastard & his $%^@* family (they are wrong to react like this. I have no expectations of mlc-er right now, but they should be mature enough to separate the issues. Your M is one thing. Your illness is another. That's it. Your illness is NOT a tool for 'vendetta or side taking', that aspect is separate & should be treated as such. Any other thinking is just 'gutter.' (Sorry to sound this way but illness is illness - how low should one go? Come on!!!)
Vge, *if one or two things fall at the 'side of the road' leave it be, maybe it has to, in the interim, so that you can 'catch your breath' to continue your journey (suggested above/post). This is your health. You are 'life raft' for your children.
Continue to tell your children how much you love them (& even during your 'not so good days' that TRUTH is there whether expressed or not) let them KNOW IT. Let them know that nothing lasts forever, ... reassure them that no matter what, they are stronger than they know & will make it. Give them the tools to make it so.
