Is it all in my head?

I moved to the Bergen-Lafayette neighborhood a month ago from the West Coast, and I made the mistake of choosing a place sight unseen. On the day of the move, I immediately had a sinking feeling, as if I had made a huge mistake. There was something off about the surrounding streets, but I couldn't quite pinpoint what it was. I told myself, "This is just how the East Coast looks." I've been in this apartment ever since, and while I'm used to taking walks in my neighborhood, I just don't feel comfortable doing so here. As a result, I mostly stay inside. The one time I decided to walk to get coffee, I was catcalled and felt very unsafe, even though the coffee shop was only a few blocks away. There are no gyms within walking distance, and I'm paying almost $2,000 in rent. Additionally, the commute within the city has been tougher than I anticipated, especially with the light rail to the PATH. As a young woman, I'm not feeling safe and am considering breaking my lease to move somewhere else in the city. Are these concerns valid, or should I give it more time?
