What can I do?

I don't know what to do. I'm so confused! I don't know what to do about my life! I don't know what I must study, what I have to focus on. And I feel so lonely! Maybe I should have a pet, or something like that.

My sister has left my parents house, it sounds very weird. She is going to share a flat with a friend, a lady. And...well, she had no reason to do it. Just told us that she needed "to grow up". Weird!

And...oh, how am I feeling? I've found that I still have difficulties to join relantioships with people. I'm still this way!

I'd like to fly to far from here.
