Do you have a good self esteem?

There are loads and loads of resources out there.. and many suggestions.. Too many to cover here but basically evaluating more realistically your skills and good points.
One way you could do that is to either ask or remember all the positive things people have said to you.. and write them down.. This in itself can help you see yourself more clearly - we are all our own worst critic and its not necessary, realistic or helpful. You can also refer to the list when you find yourself being harsh to yourself.
Another thing you can do.. is.. think how you would treat a loved one if they were struggling.. and use those same kindnesses to yourself.. we have to be our own best friend/therapist/supporter.
There's a million people out there willing to put you down.. you don't need to do the same thing to yourself!!

If I had any self-esteem would I be wasting time on a crapola bottom feeder website like this?

Since I embraced enjoying being alone without the stress of fairweathered friends, my self esteem has rocketed. And people like me better... I choose who I want to hang out with.. No more stress!

Embrace the good qualities you already are aware of. The more gratitude you embrace, the more growth you will see.

When I was young, I would concern myself with appearance and constantly worry what others thought of me, once I realized how I was restricting myself based on stupid people, my confidence soared

Become greedy, arrogant, selfish, self absorbed and self important would definitely be a sure way. 😒

At least one of these is "hinted" at in many self help informationals.

Self absorbed is quite common.

lol

Learn to know, how others perceive you .. and start perceiving others.. at the end of the day .. it's all a perception.

Better now than before

It's a work in progress.
