Learn how to be alone again

I talked to a friend last week about being alone. 'Have you ever enjoy alone time?'
'Yes, I do enjoy alone time like this, but I hate to be alone, as in alone alone.'

Loneliness is always my weakest spot since donkey years ago.
I hate to be alone with no purpose, I just hate that empty spot in my life where I have only myself.

I feel stressed recently, could be PMS, could be stress, could be the mundane life that I can't break out of it.
So I opened the pandora box.

And truth hurts.

When I thought we're going to the same direction, but the truth is we're not. We are in opposite direction trying to walk parallel.

I pictured myself to be a mother, to have purpose in life. But it all shattered when it's all just in my head.

I'm traumatized inside. It's all happening again, again and again.

I have no one to talk to, no one I want to talk to.

Please someone teach me to be alone again, please tell me it's ok to be alone.
