brain mets, help and thanks

Please help. I just got home from hospital after a "migraine" and trembling lip snt me to onc. and an mri. I just had surgery for a 3 cm tumor in cerebellum on Friday. I have 4-7 other tumors too and they are pushing wbr on me and I have been looking into this for a long time. I don't like what I see but the rad. onc, pretty much told me that "cognitive" dyfuction is a pretty moot point since I'll pbobably be dead in 6 months. I made an appt. withDr.Black at Cedars-sinai and my husband will take me there Feb.13th. What do you think? I am on Decadron now and very nervous and weepy, plus the bad news about brain mets.
