Hi jasminejave! We can't always be around upbeat people, because life does have difficulties. Even the most cheerful person will have times that are stressful.
I consider problem ownership. Their angst is theirs, and it is theirs to cope with. I am supportive, but I do not own their problems or solutions.
I live my life with the joy I embrace. When I have my own rough patches, I work hard to resolve the situation as best as I can. I purposefully seek laughter and love. I have been through many dark days, (We all have those!) and yet I am always Happy2BeHere. Without the hard times, the easy streaks would get dull. It's life. It's wonderful!
