Is it normal to be depressed even on meds?

Honestly, I'm not sure why your medication is not doing the trick for you any more. There could be many variables which might be affecting your situation. Has anything about your situation changed recently?

You said it 'suddenly changed its effect' which, to me (not a medical professional), seems unusual, so that's why I recommended you see your doctor about it. Also, I've never taken an anti-depressant, so I have no personal experience to share. I do suffer from severe and chronic anxiety, though, and I understand how not feeling well can affect motivation levels and sleep patterns, among other things. I take medication for it too, but anti-anxiety meds are a lot different than anti-depressants.

At least you are taking a holistic approach to your depression and combining medication with therapy. Many people seem to be under the impression medication alone will cure them.

This happens sometimes. Talk to your Dr. about changing medications.

It might not hurt to bring it up. As for the changing over period, it's hard to say. I'm sure everyone would react differently. For me my head gets pretty disoriented feeling and dizzy. I assume this to be from the chemicals in my brain shifting back to their 'natural' unbalanced state. But that only lasted a week or so. Surprisingly my emotions didn't seem to be effected too much.

Im currently on 4 meds and have had to change them every couple years. It probablly depends on the person but I seem to get immune to most of them after so long. Also some of them cause side effects after so long. An example is I was on abilify for a few years and was fine and then started having tardive dyskinesia symptoms and had to switch to something else (zyperixa and lithium). Ive also taken meds where I would keep getting immune and had to keep increasing the dose until the dose was no longer safe and switched meds.

i just wish the best for you, and hope you and other close to you, keep an eye on you for any erratic changes in personality and behavior

My parents made me go to a doctor when i was younger who diagnosed me with "depression" (and gave me the whole shpeal about how its a disease caused by chemical imbalances in your head) and put me on meds that I didn't need and didn't do anything. The source of my depression was the fact that I didn't have any friends, so I was like waaaa i don't have any friends, i don't have a life, this life isn't worth living. I didn't have chemical imbalances in my head, and all it took was for me to realize all of the things that I did have, and did have going for me, and that I had my computer games to entertain me and the friends that I met on them and talk to while playing. And realize that some day, I will meet a good group of friends that I can hang out with in real life, and it will be worth the wait.
I also could have easily been diagnosed with A.D.D. if I brought it up, but it's not a matter of that people can't physically pay attention in class, it's that they don't want to pay attention because it's boring and they'd rather be thinking about other things and have their eyes wandering around the room. But they/I just had to realize that I need to be paying attention, I need to get good grades so that I can get into college and have a good career.
I've also seen many people being diagnosed with "disorders" that they don't even have, and put on medication for it. Only to get a second opinion which proved the doctor wrong.
Doctors are paid to tell you things are wrong with you and that you need medication, but the fact is that human kind has gone soo many years without it, because they were able to figure out their problems themselves. But unfortunately, we live in the day in age where there's a drug for everything, and yeah, it is designed to fix your "problems" but that isn't helping you, and can cause you to be dependent on them, and can change your personality. And i've seen too many people who are fun interesting quirky people off their medication, and that is what makes them unique, therefore interesting. But doctors think that if people don't act like their expected "norm" that they need to be sedated and stabilized, but this can cause you not to be your true self, and all you really need is to change the way you think and put things into a better perspective. I myself have found the joys and perks of being an optimist, which has worked wonders for me. There's absolutely no point in worrying about things in life, as the saying goes, "If you don't like something change it; if you can't change it, change the way you think about it"

lol, is that what the doctors you pay to put you on medication tell you.
And I have to strongly disagree. The power of positive thinking works wonders. And on the flip side, the power of negative thinking causes devastating effects on your body and mind. Some weak minded people just let stuff get to them too easily, and don't know how to properly put things into perspective, which theoretically, a therapist can help you do.

then you really have no problem you are making the problem for your self i would make you eat if i were around you and that would be the only choice you would have i would make sure you don't have a chance to go make what you ate come out then you'll get a little fat. i do like skinniness tho but still not sickly skinny

i have a question for you where did you get the idea to make your self puke & why. their must be an other reason.

I don't disagree that medication can help people, so can illegal drugs and alcohol, but that doesn't mean it's the only or best choice.
