Hi Michael21 and welcome to the forum and well done in offering to help. Having terminal cancer is a very emotional experience and i would imagine having no one to support you or to talk too and being alone would make things much harder, Michael maybe this man just needs someone to talk too at this time, so maybe just getting to know him, letting him know he is not alone and has someone to talk to when he needs too will lift his motivation and his wellbeing. When you see him talk to him like you talk to your friends, don't mention cancer, if he wants to talk about it that's ok and please don't say thing like, your looking well, how are you feeling or are you ok today. Michael i have terminal cancer and am 100% independent and maybe this man is as well and is going through a tough time emotionally at this time. I am sorry to hear of your mental health issues and your recent feelings, though i would see being over concerned as a sign of a good person, I hope you are able to help this man and who knows you may help yourself as well, take care.

Eddie
