Is it possible to be COMPLETELY accepted for who you are?

Yes it is but you need to accept yourself and be confident in who you are. Once you accept yourself, does it matter if others accept the real you?

As soon as you give up your expectations of others.

You are who you are. Nobody needs to accept you but you. You're perfect just as you are. No need to be anyone else. If people don't like it, they don't have to look.

Questionable, since no one will ever [i]completely[/i] know everything about you.

Yeah very possible. It's not the easiest though because very few do but 1 outta a million will

Yes it is. Surround yourself with the right people and then start by loving yourself.

Be gentle with yourself you're doing the best you can. 😎☮

its very difficult to stay true to who you are 100% and not have people judge you

Why would it matter if they didn't?

Not by everyone 🤷‍♀️

In my case probably not I ain't the easiest guy to understand a lot of the time and my mood tends to fluctuate quite a lot

yes it is but not by everybody, there will always be one who won't be accepting
