Flossom,
It is difficult to grasp all the options at this stage. For me, I was actually online looking for another loan option, when I came across a site for people in debt, out of curiosity I entered my details, I then started getting calls from companies talking about bankruptcy, debt management plans, IVAs etc. I didnt feel comfortable, as they were calling me and the IVA, for me, sounded too good to be true and wondered if it was a scam (it wasn't by the way).
I think you are in a better position in that you have found this site, with real people, talking about their experiences, that you may relate to, with recommendations of people/companies to talk to and even how you want to talk to them (phone, online etc).
There is another thread under the "See the last 250 debt posts" (link at top of page), from someone at a similar stage to you, asking a lot of good questions (as we all did at the start), with good responses from Forum members. Its titled "Thinking of IVA, need advice", definitely worth a look.
