Obviously saying "hi" to someone or nodding to someone, even just making eye contact can be hard.
However, there have been three occasions when I have been able to say "hi" first, nod and wave.
After that, I was greatly surprised that for 5-10 seconds afterwards I genuinely felt slightly happier and even noticed I smiled almost instantly after as well.
Previously none of this would have been able to happen. Two would have happened.
Firstly, I would have kept my head down or pretended I didn't notice them. Or secondly, I would have awkwardly made eye contact and instantly looked away due to eye contact feeling extremely weird (which it still does.)
After 15 weeks of these sessions, not only I but my family have been able to notice a difference in me (I smile more and sound more confident). I never thought that I would have been able to come so far in a short amount of time.
Even a couple of times I have been able to ask friends if they wanted to do something at the weekend; I also feel that due have friends unlike in the past where I felt like they were just there as 'acquaintances' for school to make me not look like a loner or that I was wired.
I'm glad that I had found this otherwise I wouldn't be at the stage I am.
