Tweety,
Like a few people said in here, the doctor isn't necessarily marking you as a crazied patient. S/He only had suggested that perhaps you would check-in the hospital and stay for a week or two. At least it's not longer. I'm sure they just want to see how you are in a stimulated/non-stimulated environment. I don't think the doctor was necessarily marking you as attempting suicide neither.
Go ahead and get an second opinion. If the second doctor suggested it as a possibility, then I would encourage you to try it out. It seems (from what I have read and heard so far) that it could be of benefit to you. A stay at the hospital won't be on your criminal records and no one else really has to know about it.
Mental hospitals aren't so bad as they used to be in the past (think "One Who Flew Over the Cuckoo Nest" or "Girl, Interrupted"), I don't think they're going to drug you up so much. I believe the doctors will just explore what could be of help to you, because different anti-depression drugs causes different side effects. Believe me, I've seen it, and sometimes it wasn't pretty -- I knew someone who got back on meds and trying a new one and she acted bizarrely. If the doctors could observe that they could do something about it.
Also, another suggestion from me: Was this a medical practicator that you went to? Or a psychotherpist? If it was a medical doctor, then perhaps you may want to consider going to the psychotherpist (those with medical degrees but specialize in psychology, and allowed to prescribe medications) because they go through with a lot of depressed individuals and may offer the best alternative.
As for interpreters, I agree with some people who said that it is not wise to bring your mom as the interpreter... I know you don't trust other interpreters, and that there are very, very few of them in your area, but mom does kind of violate the private patient act. Who knows, mom could have been telling the doctor other details about your depression and suggested for more help from the doctor, that's what a concerned mom would do. Perhaps you can just have mom join you in the room with the interpreter and let her sit there. Or how about finding a peer interpreter? I used to interpret for a deaf man at a hospice and he very much appreciated it because I am also Deaf (but able to read lips well and interpret).
Depression is very common nowadays -- I believe there's just too much stimuli that causes that, unfortuately. I've suffered depression, gone to counseling, and wrote a lot. Now, if I'm just not happy, I find other ways to make myself happier or I leave the situation where I'm not happy. At least that's what works for me.
Tweety, I know you'll find your way out of this "funk" you're in.
My best,
KJ
