OMG12, love your post!
Myself - I thank God every morning while sat outside with my first coffee of the day. Just for my kids, food in our tummies, enough money for bills in the bank, lost loved ones, my garden & wildlife etc..
Downsize - I moved to a cheaper, smaller house & love it. It's closer to the city too so taxis are more affordable (I sadly don't drive - LEARN!)
Be tolerant. Things on the whole just aren't worth upsetting yourself or others for. On the other hand, I echo PP's who advise saying NO to people when you don't want to do something. Luckily I find this easy!
Do things that you WANT to do - try not to put those off. Things that make you laugh with glee like a child! They do us SO much good!
This one might get me shot down in flames - but, how do your friends make you feel? I realised a long, long time ago that I'm happier alone. I love keeping in touch online, so I can help sort problems out AT A DISTANCE. We all have problems, I tend not to share mine, who wants to know?!
I'm a widow so understand PP's feelings re being lonely. It happens now & again. But I was lucky to be adored, I don't think I'd find that again even if I was interested in finding someone else, which I'm not. I ask myself if I'd want someone watching F1 or something (ugh) or wanting me to go to a pub all the time (ugh) what time dinner is, (when I'm often happy with a sandwich) or, as a PP mentioned, someone asking if I was ready to go up to bed in the evening. I soon start thinking of myself having freedom rather than being lonely!
