Hey, just get off your butt and do it.
Nip along to a few karaoke nights, the 3 minutes of pain now and then will be really good for you and show if you can go further.
Those songs you have recorded. Think about where you want to go musically and choose 3 or 4 tracks you think are your best in the type of music you want to perform.
AT THIS POINT, MAKE A COPY OF YOUR SONGS. If they are not subject to copyright, the best thing to do is put them in an envelope along with a lyric sheet and dates recorded. Seal the envelope well and post it to either yourself or a solicitor - if you have one.
This may sound daft, but ensure that the envelope (once it has been delivered through the post) remains sealed. The postmark will show that the songs were written by a certain date, should someone you send them to try to pass them off as their own.
Once you have your envelope back and safely stored, send another copy to managers, agents, record labels etc.
The most important thing is to get the songs and yourself heard. Also, to have more confidence in yourself. If you really want it, you can do it.
Good luck.
