Being older, my childhood was pre Internet. I remember a time without technology on demand. It is, as you say, a blessing and a curse. Bullying, fat shaming, etc, existed in my high school but instead of being on social media, it was delivered in person, to your face, by people bigger, or richer, or thinner, or more popular, etc. Back then you could avoid a bully by changing your location. Not so, now. Social media is everywhere. You did not describe the specifics of your anxiety but I suspect from your writings that technology is partly to blame for your anxiety. While it can do this to a person, it can also undo it as well. Look at all the support you are receiving right now from total strangers. There are many Youtube videos on meditation, self hypnosis, music therapy, working out, etc. that are all effective ways to reduce anxiety. If technology is the cause of your anxiety, it can also be the cure.

I laughed at your statement about everyone snapping photos with their phone instead of living in the moment. It is so true. When you identify the problem you are half way to the solution. I have several very close friends and an amazing wife. The social relationships are crucial for our mental health. Not as a co dependent, who has a neurotic need for approval, but as co equals who enjoy the camaraderie of being together and sharing our hopes and dreams while celebrating our victories and consoling one another when we lose. I hope you feel better soon.
