The amount of worthless advice in this thread is amazing. Suggesting trash like blockchain.info as a wallet provider, which goes against the very nature of Bitcoin is absurd.
can any one tell me how to use bitcoin core qt without download the whole 40gbblol

If you want to reap the full benefits of both privacy and security you have to be verifying everything yourself. This means that you have to download the whole blockchain, which is about ~100 GB today. If your bandwidth is somewhat limited, you could spread this download out over a couple months and use something like Electrum (not web wallets) in the meantime. If you have storage capacity issues, then you can use pruning which will take up only about 2-3 GB of space. However, this does not save you from having to download everything.
