For what it's worth, you really do sound like you're doing all that you can possibly do. The only other thing I can really think of is nutrition - if you're good at cooking, home cooking especially with good anti-cancer foods is always a plus 🙂   As for having fun with your friends when she's not there.... it's incredibly difficult but truly do try and find a way to enjoy yourself.  I don't expect miracles from you as I also find it really difficult to enjoy things with the shadow of cancer seemingly looming over my family and I. But honestly - it has helped me to include things that aren't related to it and it might for you also.  In my case, I started an online course - only 5 minutes every day or so because of my own feelings/turmoil but after a week and a bit, I am not feeling so awful about it and actually beginning to enjoy it.   That being said, this approach may not be for you but do please do give it an honest shot! (Just make sure to take it slow and easy. In the case of friends, maybe a quick 30 minute catch up?)    Or if it seems too much of an ask, perhaps consider maybe seeing a psychologist for yourself to help you find a balance between dealing with your gf cancer and your own life.  There is no shame in it!! Mental issues are as important as physical issues and should be treated as such. 🙂   Either way, wishing you plenty of luck and good fortune.         ... View more
