Coma

I listen to virtually all music, whatever I can get my hands on. Of course there is a lot of music I dont like, but no specific types. My favorites range from assorted classical, Buckethead, and Matthew Good. As for what style I would like to compose in, is whatever is currently in my head, and that also includes everything. I am interested in learning how to sing, would that be a start to learning theory? Or at least assist?

I've been very artistic my entire life but recently in the last two years has music been a huge part of my life, and in the last year almost consumed me (in a good way). I've never been educated or taken any sort of lesson in music, I bought a acoustic guitar 6 months ago and only played it for a month or so but I only experimented with it starting with very simple melodies then building off of it in my head. For Christmas my girlfriend got a violin and boy what a treat for my mind that was to try... Last year I have been composing music inside my head and its been growing into my daily life and dreams stopping only when in moments of strong concentration or while listening to music that affects me (sometimes I even build off of it or manipulate it). Since last year I have had a strong desire to write what I hear however I have no idea what to do, I've made attempts at writing in home-made ways but obviouslt failed. What I want to know is where I could start. I would like to go to school but cannot afford it... are there any courses that start with no experience in music? Would I have to enroll in adult-ed and start from middle school level? Thanks in advance.
