Lose the final stone. Get back into fitness. In the summer I spent a few months exercising regularly. I looked so much better, but mentally the effects were miraculous.I felt in control and much more positive than normal. I still exercise but in a desultory way so the effects have worn off a bit, so I will be stepping that up.
Limit online activities and return to books, my first love which has been elbowed since I got a tablet a few years back. And use the phone as a communication tool and for info in transit, not an excuse to surf the net every time I am a passenger in a car or on a train or in a cafe etc.
Do something creative. It might just be a bit of knitting but it gets me away from screen time.
Stop trying to win people over. That old saying, those that matter don't mind, those that mind don't matter. Where I work I am like a square peg in a round hole. I contort my personality to try and get people to like and include me. It is stopping. They never will like me, they are not my cup of tea either, so why on earth do I creep around trying to get them to change their opinion. I have gradually stopped the last few weeks and like getting fit, makes me feel more positive and in control.
Live in the now, stop projecting ahead or expecting the worse.
