If you try and fail,It should not be a reason for giving up music,you may fail not because you are untalented,but for many other reasons.
I havent listened to your music,so my advice would be the same as I would give to anyone else.
try and see how it goes,also try and develop other sidelines,perhaps playing guitar in a ceilidh band,or teaching your instrument,so that you heve some other regular income,that is compatible with your solo gigs.
when I first turned professional in 1976 ,I played regularly in ceilidh bands,if I had no gigs for a week, I had band gigs.
another line to think about is calling for dancing,or even dealing in musical instruments,to supplement lean times,while your solo career is getting established.
becoming an established artist always takes time.
If you live in England Geographical location is important,it is much more difficult living in Cornwall,or Caithness,than Nottingham.
