How does one find a mentor in their chosen field?

I used to fancy myself independent and autodidactic, and I am for the most part. But I have become rather frozen and without a sense of direction over the past few years, and feel like I cannot do it on my own anymore. I have a lot of trouble letting myself receive help, for one, so this is hard for me.

I would love to find a mentor, someone who I could look up to but not be envious of, who would help me find a direction for my talents (singing, writing, art) and accept me for who I am, and just generally encourage and motivate me. But how does one find a mentor? I have no idea. And I have very limited income, so paying for one is a problem. Are there websites or resources for finding one? I am rather hermit-like and don’t go out much, so I don’t like the idea of stalking out “the scene” here in Charleston to find someone. Any advice is helpful.
