I post this diagram to help illustrate what Melanie already pointed out.
Nice to see the modified diagram but U have missed a vital component.
There should be small resistor like 22 Ohm( Ur LAW) to 47 ohm in serries
with 1uf/250V capacitor ( Melani wont approve of this ).Otherwise in few
days that capacitor will be reduced to open circuit (if of metallised film
type) or get short (if Film foil type) and whole ckt will go up in smoke.
The resistors should be atleast 1/2 watt type ( 1watt better). A high value
resistor like 220K is better placed across capacitor to protect user if he
accidently touches capacitor even when ckt is disconnected from mains.
