Uncovering the stress

I've got things stressing me out, and I have been trying to delay dealing with them.

That includes the relationship I have with this girl.
Making payments for school and OSAP.
Roommate issues.
The issue with missing books that I borrowed from a teacher.
Schoolwork.
Myself.

I need to deal with them when I am alone.

When I have friends that talk to me about these issues, I try to sort them out on the spot.
And it works.
But how about learning to do it on my own time.
To sort things out by myself, without relying on others.
