Your thoughts reflect my own completely. I, too, feel lonely and isolated, especially since I have lost most of my friends and family. I'm 81, but age isn't important, really. Mainly I read, watch TV or spend time on the internet. The problem is that I'm always alone so life hardly seems worth living. Like you, I just try to get through the day. I live in SW Florida, but no longer go for walks on the beach because of back problems. I'm sorry you had to go through a hip replacement by yourself. That must have been very difficult. Take care.
