Missed opportunity

I feel like I really blew it. I like my job, I actually love it, it’s one of my favorite places to be hands down. I love my coworkers, and especially my boss and management. I wish it wasn’t seasonal, because if I could I would work there every day all year round. But I can’t, just about 2 months out of the year and a couple off season days/special events. Recently, they told us they would be promoting more leads, and that anyone could apply. This will be my 6th year with them, I never call out unless it’s an emergency, I don’t want to sound like I’m in love with myself, but overall I work really hard and am very committed to this job. I wanted to apply, and take an interview to be promoted but I chickened out. I just couldn’t help but think about how many other people would apply, and how there were so many others better suited for the position, maybe it’s just a complex with myself but I felt like I was just not enough. Even though I wanted it, even though I want to move up in the company chain, I just couldn’t get myself to do it. Living with anxiety like this really sucks, and this is me medicated, I wish there was just some pill that would really make all of the anxiety go away. Anyways, I just feel worse about it now because my coworkers, including one of my supervisors, told me that had I applied I pretty certainly would have gotten a promotion.   : (
