Welcome to the forum Rapine and well done on taking a positive step towards addressing your problem.
DarkEnergy has laid out some good initial steps you can take. I would also strongly suggest attending one of the New Members Practical Advice Group On Mondays at 21:00 (UK) and Thursday at 19:00(UK) that Dunc mentioned. I found these a great resource when I first came to the forum and was looking for some guidance on some steps I could take.
