Hi Lidia - We DEFINITELY understand, so much that we have a whole forum dedicated to those starting out with less to lose than others...our Featherweights forum. Head on over there and check it out!
We also had a Support Group going for Short Chicks, so you may want to search there...
In addition to those places that cater specifically to your situation, we have more general groups by age range, eating plan, etc. Jump on into any or all of them.
I'm glad you found us and posted!
