I'm so stuck

I don't know what to do
Why am I going through this again?

I'm so stuck with this situation
I feel like I'm going back to my old life
So stuck and can not go anywhere
What is wrong with me?

I hate myself for being like this
Why can I just move on and live my life without being depending on him
I want to be me
I just want to have my own life.. being happy without any burden

How am I supposed to live my life if  I'm still stuck with him all over my mind
Why am I so obsessed  with him?
I know it's not right, but he fills all my head
I know I can't have him, but I want him

What should I do?
How can I live a good life?
Can someone tell me?
Can someone lead me?
I'm so stuck
