Glioblastoma IDH WY

Hi 

3weeks ago I was admitted to hospital with headaches and weakness to my left side. 
To cut a long story short I has surgery to remove a large cystic lesion. They removed most of it but could not operate on all of it due to the location. Subsequently told it Glioblastoma WHO GR 4 IDH WT. 

Got my first oncology appointment next week and am unsure on what to expect. Anybody else got any experience of the tumour and any tips on trying to cope with the diagnosis. Any info or advice would be really appreciated whether it be dealing with treatment side effects etc

many thanks in advance
