I'm not sure

Hello. I'm not sure what I have and would like to check here before I go to a psychologist. I'm a guy 19 years old and I've been experiencing mood swings. These mood swings are different from normal emotional response. First of all the mood swings changes by days. Eg. One day I'm over the top and the next day I'll be so depress for no reason. The second thing is that when my mood changes all my energy will be drained. Thank you for your time and I hope my problem is not a big deal

Hi sazerjob.

I understand your concern and think you're doing the right thing by seeing a psychologist. We can't tell what's going on with you and the psychologist will be much more adept at it than we are. I did want to say, though, that there are some physiological things it could be and it's important to get checked out physically also. ***I'm not trying to suggest you have this.***I say this because your saying your energy felt drained reminded me of my brother's anemia, which turned out to be something serious. Again, I'm not trying to suggest you have it, I'm just trying to underline the importance of getting yourself checked out.

Yes, I agree with exiled, you're definitely doing the right thing to seek help in figuring it out. Even if you just start by going to a gp, they might run a few initial tests to "rule out" the most common causes of these kinds of symptoms to ensure that you're proceeding in the right direction.
Here's a web quote that explains it better than I can: "When a person is diagnosed with an illness, doctors do something called a differential diagnosis. Basically, this is when a doctor considers all the illnesses that may explain your symptoms and then decides on which one fits best. In the case of bipolar disorder, part of the differential may be considerations of anxiety disorders, Cushing syndrome, head trauma, thyroid disorders, and many others."
So my advice, from my experience, is to trust the process. Make that appointment and just keep putting one foot in front of the other, and you will get things figured out! Just be prepared that it is often a bumpy road of diagnosis, mis-diagnosis, re-diagnosis.... just know that this is normal and it is ok. And stick to this forum. I could have made more progress so much sooner if I had found this place 8 months ago!

Wow anaemia.... maybe I should go to a doctor rather than a psychologist. Thanks, I'll do a blood test to see what's the problem

The general path is to go to a GP first and let them refer you to specialists.

sazerjob, this is why we can't diagnose you online. None of us has actually seen you. None of us had a chance to ask you questions for an hour. None of us knows your medical history. And it's pretty likely none of us would have a clue what to do with it because we are not doctors.

As Exiled. says, go to your GP, tell them how you are feeling and let them make a decision what needs to happen next. Good luck -- and big hugs.
