Definitely give up social media if you can. I came off FB last year and it was amazingly freeing. I'm still on Twitter but I've culled massively.
Also, yes, cut down on the texting if you can.
I think it's a change of mind-set to be honest which can be very hard to achieve. I grew up in a house where appearances were everything so I assumed everyone else was judging me the way I was encouraged to judge other people. It was a light-bulb moment for me when I realised that no-one actually noticed or gave a shit about me. Those who did notice and judge me, did so for a few seconds and then moved on with their life.
I also started to really think about whose opinion I actually care about and realised I actually, genuinely give no shits about almost anyone's opinion.
Making a list of people whose opinion matters to you is very cathartic and, hopefully, should take you seconds. For each person on the list, ask yourself why do I care about their opinion? and what are the consequences of them having a bad opinion of me? and does this matter? So, finally is it valid that I care about their opinion?
Example: I care about my colleagues' opinion of me.
Why? Because I want them to see me as competent at my job
Consequences: They'll think I'm shit, report me to my boss and I'll get fired
Valid: Not really as the chances of them reporting me AND then me getting fired are quite low. Plus, if I am going to care about their opinion I should only care about their opinion about my work, not my hair, my personality, my clothes, my hobbies etc....
