Basically, I feel that I have not much value and so I feel myself small. It is like what happens in the world is really none of my business. I would not say I have depression, it is just I think many things do not matter at all.
You matter greatly to yourself. Don’t punish yourself by comparing yourself to gigantic things.
I’m sure the impact you have had on others will come to light if you think of it. Even the support or insight you have offered here has helped someone in some way. We all have worth and yours is priceless.
