Hi Laura,
Personally I think the decision of when to have DBS is a personal one and only you can answer the "when" part.
Compliance on your part and a healthy positive attitude which you seem to have from looking at your posting is also (I think) desirable if not a necessity.
I had DBS 6 yrs ago and will be forever grateful for the normality it allowed which I'd up until then thought was gone for good.
One of the group members here Charlie founded a website called yahoodbs...whatever. Help me out here Charlie! You might get some help from them esp. if you're in U.S. which the majority of the members are.
