I'm Worried About My Future

I joined this premium job search website that is said to work. I applied for ten positions yesterday and only heard back from one telling me I didn't get it. I used to think if there were a lot of opportunities, that would increase my chances of getting a job. But now I'm only thinking it will increase my chances of getting rejected. Rejection comes so naturally than something working out for me. Happiness comes in short supply for me. I was happy when I found this website because I thought maybe it was a sign of things to come but now I'm starting to think this could just be another opportunity for me to get hurt again.
