So if i give my account as a collateral? do i give the password or they will just give me negative trust if i cant repay it??
Depends on a whole lot of factors:
1) do you trust the lender... If you do, you can give your user/pass to him/her, if you don't: it's advisable to use a trusted escrow to hold your account details
2) if you default, the lender now owns your account. He can give it negative trust, or he can try to sell it to recuperate his financial loss
Last but not least: hasiramasenju already said this: you cannot get a loan with a newbie account... It's worth literally nothing (less than the miners fee required to send you the coins).
In your case, however, the account has "some" value, since it has "some" potential activity:
