it seems everytime i sent the correct value to the correct adress, another transaction was also made with a much higher value? i don`t get it
You have nothing to worry about, since the second address to which a large amount is being sent is the change address that you own. Since you are using Electrum, you need to go to the "address" section and there you will see all the addresses where your coins are returned.
If we assume that the second address to receive is not a change address, then in this case the loss of the OP would not amount to $600, but many times more, since it was debited every time a transaction was made. But the OP does not write that he lost several thousand dollars.
