Trouble saving money

I have been trying to save some money, sound simple right? To me not really, due to some background I have hide my money from my family to be able to have a chance of reaching my goal. And every few days I check up on the money I have save up. Something money been missing in the wallet I put them in, it's not a lot but still....The fear of one of my family members knowing I have a savings is stressing me out, I worked hard to save up that money and I'm scared of losing it if someone in my family knows and jus secretly taking a small some every now and then.
