Go to NY!!

Every single day, I've worked really hard.
I can't think anything when I arrive to my apartment, I just fall asleep.
I feel I have been under stress. And my stress level has increased, a lot.
I wonder what should I do to relax.
Can I relax if I spend time for only myself?

I'm going to go in NY next week.
unfortunately, my boyfriend decided to give up visiting U.S. with me because of his disease.
I felt really sad, but I'll enjoy trip by myself.

I can say the only way I can relax is I go to the trip!!
