How Touching.
Hae.Um..That wuz v v touching.Chow.
How I did it: I tried seeing things in an objective light, ie each side, not only the negative one getting me down at that moment. I rationalised, putting my feelings in context and seeing the bigger picture.
I also told myself that most people are kind given the chance and support, so didn't take negativity too personally and managed to dig deeper into the kindness of strangers.
Lessons & tips: well, first of all, know your worth. If necessary, write down positive affirmations about yourself, and read them regularly.
secondly, assess your view of the world and find out which areas are problematic, such as social situations, or talking to strangers, or perhaps feelings of helplessness, lack of motivation, or victim-mentality, procrastination, etc. Whatever it is, you can face it head on.
Thirdly, be objective and realistic. Try to put your emotions into context and understand why you feel the way you do. Then see if you're being rational, and not paranoid or insecure, or a bit prejudice.
Once you've managed to reach this stage, you should be able to handle things as they come.
Resources: Diaries and notebooks can be useful to some, some products like shampoo to make you feel just a touch better, a good night's sleep, a friend when you need one.
These are things that help me personnally. A psychologist can also be of great help, provided you feel comfortable with them.
