"According to Reddit” - so many lives have been ruined listening to what gremlins on social media have to say. It’s simple. If you want, approach. It’s not dangerous, you won’t get cancer. If they don’t want to talk, you will stop talking with them and talk with someone else. "I am deeply afraid of irritating someone or being in awkward situations." - anyone who thinks like this is suffering from abused dog syndrome…
I mean, social anxiety - the neurosis itself - is just this. People haven't "lost at life" for having a mental health problem. I think it's quite commendable that someone can recognise their own shortcomings in this regard and work on it in a positive light.
What you might find easy, someone else might find exceedingly difficult - for example, people who find it difficult to keep up their health when they are clinically depressed.
