when history starts repeating itself

There are parts of my life that i thought I had dealt with and were securley in my past. But how wrong was I! I thought I had dealt with it all, sorted it, basically been there,done that, got the t-shirt. Well looks like the t-shirt is coming back again.
I never wanted it to get like this again, I thought that I was strong enough to deal with it all.
Looks like I'm still not strong enough, with the salt backs in the wounds again.

Why am I surrounded by people but still feel like I am alone?
