Hi Siyo,
I don't know a single person in recovery who hasn't felt scared that they would not succeed. I think it's good to have a healthy fear; it means that you recognize how powerful this disease is, and how it truly can be cunning, baffling, and powerful. But remember that just because we are powerless over alcohol does NOT mean that we are hopeless in recovery!! Trying an AA meeting is really a great idea, because you are likely to find a diverse group of individuals, some of whom have many years of sobriety, others who are just starting out, and all levels in between. Hearing their stories is a tremendous help and relief for me, because it shows me that stopping IS possible - one day at a time. Don't think in terms of forever; just go day by day. I no longer make promises to myself or others; I simply say today, I will not drink. At first it sounded like irritating dogma, but honestly it works.
