1- A treat need not be a material thing. Just because others buy themselves things, doesn't mean you're depriving yourself by not following suit.
At least, I hope you're not depriving yourself because you are deserving of all things that bring you joy.
A treat can be the fact that you're
respecting yourself enough to only buy things you are certain of, or allowing yourself to browse without giving in to the pressure to buy.
A treat can also be allowing yourself to enjoy a quiet moment, a good book, the company of good friends. I don't think retail therapy is always a healthy treat (I used to indulge in it and wish I had better outlets for stress at that time).
There are many ways to treat yourself and I've learned that self-care extends beyond buying something nice. Of course, purchase what you enjoy- life is to be lived- but know that self-care comes in many forms and you shouldn't feel the need to do what others are doing.
2- I am not really on this journey at this time... as I mentioned in an earlier post I am unable to edit my closet presently because I don't want to hurt people's feelings (they gifted me the bags). However, I still contribute here when I feel I can add something useful (which I hope nobody objects to). There's no need to watch silently. Join in, chit chat, we all learn from each other no matter what stage we are at on this journey.
I have only been active on this forum for a short time but the community here is outstanding. I feel honoured to be a part of it, whether I'm just watching or actively contributing.
