LittleBuddhaTW is giving good advice here. Be sure to follow it. It's tempting to lay back and not do anything about it, when you're down, but going straight to the doc is the best thing.
Go to a major hospital. Gaoxiong has Chang2geng1 yi1yuan4 (Chang Geng Hospital) and Gaoxiong Yi1xue2yuan4 (Medical School Hospital). Both should be very good. Here are the phone numbers for the mental health clinics there:
Chang Geng (07) 733-0961
Medical (07) 320-8221.
If you have any trouble communicating with them, PM me and I'll call to make an appointment for you and PM you the results.
Just remember, it doesn't mean anything is wrong with you, or that you're somehow not "strong" enough, or some kind of BS like that. Think of it just like having a cold - when you've got a cold, you take cold meds; when you've got the blues, you take blues meds. No stigma, is my point. Of course, other therapies combined with medications will help you the most.
How long you have to wait varies with each drug; if you're topped out, talk to your doc, and see whether you're really topped out, because they don't always properly inform patients what the max recommended dosage is, or what the time period is before improvement. And as LBTW suggests, if you're topped out and have waited long enough (I'm guessing 4 weeks, not 2, but the doc and others will know better than me), then yes, ask your doc to switch meds for you. If you ever feel suicidal, don't wait the 2 or 4 weeks!!! Go straight to the hospital immediately, and be sure to tell them your suicidal feelings. They will help you, don't worry!
BTW, the Taipei Times has a relevant article today, "Taipei City offers help to sufferers battling depression":
Note that they list a 24-hour hotline, but you could call it from where you are, too! 02-2346-6662. I'm guessing they might be able to help talk you through rough spots, and might be able to help refer you to someone where you are for face-to-face consulting, too.
