I was just doing some reading over the weekend about the value of allowing ourselves to feel and accept uncomfortable emotions. Society is very "positive pushy". It's seems that we're almost programmed into thinking if we aren't feeling happy and content, there is something wrong with us. I believe sometimes we should allow ourselves to be comfortable with discontent. By pushing it away or thinking something is wrong with it, we're pushing away the things and events that caused us to feel those things.
Maybe your strange feelings should just be allowed for a bit. Accept them. Know that they aren't strange because they do have meaning and represent part of your life.
If there are senior social or recreation centers in your area, maybe you could check them out.
Maybe going to sit at the park would feel nice.
If I were nearby, I would come pick you up and go to the park with you.
