answer:I think for me if something is comforting or pleasant in any way then it is fun no matter how big or small the thing might be. I do allow myself to have fun, but it does not have to involve something spectacular as it can be something as simple as doing a crossword or something that takes that little bit more preparation like going for a walk in the hills. The chances are you do already know how to have fun, but maybe because of your friend you look for something bigger and better without being aware of even doing things already that you enjoy. Look at your interests and how you can incorporate them into something that is fun to do as it can take some of that feeling of stress or worry off you. I know myself that I will even just go and walk into town and back home with my ipod on just to get some fresh air and nose at what is going on or I will do stuff in the garden as it relaxes me so you too will have things that relax you.
