more often than not i'll try to suppress these feelings and move on with life, but at the same time it's like i can feel bad for myself if i want to. is that selfish ?

don't compare yourself to others. 99% chance all of your problems and troubles are valid and you shouldn't prevent yourself from processing those emotions and feelings just because "it could be worse"

this just means you're a decent person op. but you're allowed to feel bad for yourself regardless of how good you have it.

Most finna say it’s not right to think that way but I believe you should

You would get tired counting all your blessing
