Your timeline of events makes your question difficult to follow, and I'm no Sherlock Holmes, but what follows is what I suspect happened:
A) "I did something completely dumb and fell for it because I wanted money. I gave
away my bank account login to my sugar daddy."
You gave away your username and password to your bank account (savings or checking)
because you wanted money (balance in the accounted unstated, but assumed to be more
than one dollar), to another person (sugar daddy) on an unspecified calendar date.
Sugar daddy accessed your bank account one or more times (succeeding in
removing/transferring monies out) for an unspecified passing of calendar time.
** B) and C) could be reversed **
B) "I only had a dollar in my account. I know my bank account is "already" in the
You had access to the bank account for an unspecified passing of calendar time and the
last time you logged in you saw the balance was one dollar and possibly pending
account fees and penalties that would put the balance below zero.
C) "tried to use it and now it’s suspended. He claims it’s because he tried to login
You attempted to access the bank account after an unspecified passing of calendar time
and received a message that the account was suspended, and was unable to login.
You somehow, either by calling bank, statement or sugar daddy, discovered that your
account balance is/was one dollar, and know that account fees or penalties
from unknown times of use from sugar daddy has put the account balance below zero.
D) "I hope he didn’t do anymore damage."
You know or suspect from sugar daddy that it is only financial loss.
E) "My parents would be so disappointed as I'm 17"
You are under 18yo.
F) "I have no idea what to do."
You do not know where to start to fix the bank account and/or financial loss.
If this appears to sum up your problem and question then this is my response:
Sit down and have an honest private conversation with your parents as quickly as you
can manage it. You said your parents would be disappointed. That is understandable
wouldn't you agree? Evidently your parent's guidance/feelings are important to you,
otherwise you wouldn't have mentioned them, or you would have said they'd kill you.
Since you didn't say that, I would assume you have a reasonable relationship with
them. Also disappointed could mean that they see you as a mature and responsible
child and that your bad decision was less than they would expect of you.
You used the term "sugar daddy" to describe the person you gave the information. My
understanding of that definition is: An older man by at least 20+- years or more,
unmarried or married, that has money, among other assets, that he entices or spends
on a young girl, 16-18yo, giving her gifts and/or promises typically for sex in return.
For whatever reason(s) you are with him, legally or not, you are in a relationship
that either your parents know about or you've hidden it, and this too would be the
further cause of their disappointment. Both the bank account AND the relationship
must be revealed to your parents. You already know these things otherwise you
wouldn't be looking for other solutions.
Your parent's ARE the solution. They love you and have spent 17 years teaching you to
make good livable decisions so that when you are on your own in relationships, at
college and life, or whatever else, you will be safe and happy, even when they are
no longer able to give you guidance and counsel after they've died. That is THEIR
Your PARENT'S are the solution. Even if I have misunderstood your relationship with
them they are the ones to take the lead and talk with the bank and police if there
are illegal activities with your account. Tell your parents that YOU would like to be
involved so you can learn from this mistake.
As for sugar daddy, that's between you, your parents, and the law if necessary. Even
if there are no illegal activities with the bank account, if he is a decent but lying
individual, you and your parents must decide if he has broken consent laws and
whether the law needs to be involved. If you have a good relationship with your
parents then continue to trust them.
I know this was a long answer, but life-learned lessons are very seldom short
Update: Having joined this exchange I realize that the expected answer should be about banking details... I stand by my answer. Tell parents.
