How do you know when to hang in there, or just simply let go?

Edith said it would never be the same again. Sinking it in, knowing the fact that it has got to be that way sort of breaks my heart.

Certain things in the world can definitely break my heart and drifting apart from the one very best friend is one of them. We were so close and it felt two worlds apart and I've got to live with that. Oh...I'm crying on the inside and on the outside.

I kept asking myself 'how do I know when to hang in there, or just simply let go.' But there is nothing simple letting go, so u have it! I was trying to figure out what has gone wrong. I was trying to fix things but the power is not in my hands all the time. We both have grown into two different persons and our 6-year of friendship cannot survive that. I feel incredibly sad having to accept that!

There's a song said..'U want to come back but I want nothing' and that looks like what is happening with us right now. Well, it doesn't look like it leaves me any choice. Now, do I hold on to the love and friendship we had ? Or do I let go...hurtfully?
