Hi Shashasha!
I noticed you're new here as well as new to forums in general. I suggest you take a look at this area:
http://www.3fatchicks.com/forum/forumdisplay.php?f=40 just to help out a little with some Frequently Asked Questions & such.
You'll find a lot of different sections on 3FC, so it may take a few days to look through them & find out where you belong.
You've already found the UK Section
which is great! There are also support areas based on age, amount needed to lose (like the 100lb club), interests, there's the Diet Central area where you can find members following similar plans, etc. So much!
And don't hesitate to post wherever you're comfortable.
Think of a thread as a topic, and if you'd like to reply to the topic, just hit "post reply". There are various sections & sub-sections, but if you keep coming back it'll be like second nature to you shortly.
I'm so happy to see that you don't think of this as "pass/fail" this isn't an "all or nothing" area. Weight Loss is going to come with some bumps in the road. We have to continue on.
Keep posting & best of success!
