This may sound stupid, but depression or tumor?

I've technically been diagnosed with anxiety/depression with the possibility of some ADD stuff from they psychologist, but I can't help but feel that there might be something else going on. The general symptoms are: foggy brain, little energy & motivation, less social than I used to be, difficulty concentrating, my head feels like it's being physically stressed like there is a rubber band stretched around my brain, some difficulty with memory, lack of confidence, zoning out, not mentally sharp, etc. Occasionally, these symptoms go away and I'm mentally sharp, I feel good, I'm alert, communicate well, 'that smart kid', etc, but most of the time I'm stuck with these symptoms. I've been on Citalopram for a little over a month now with pretty much no change. I tried taking some Amoryn also with no results. Normally, I would just say that I haven't found the right meds, but it's the brain feeling physically stressed that worries me a bit. Here are some symptoms of a tumor:


New onset or change in pattern of headaches - perhaps this is the brain ache stuff?
Headaches that gradually become more frequent and more severe especially in the morning - sometimes I do have a nasty headache in the morning
Unexplained nausea or vomiting - occasionally I feel a bit nauseated, but I think that's just hunger pains, or typical stuff
Vision problems, such as blurred vision, double vision or loss of peripheral vision - eh...not really, but occasionally some blurry vision when I get tired
Gradual loss of sensation or movement in an arm or a leg - again...not really
Difficulty with balance - occasionally, but not on a regular basis for sure
Speech difficulties - I seem to have increasing difficulties communicating verbally and saying words correctly
Confusion in everyday matters - yeah, but depression does that too
Personality or behavior changes - yeah, but again, depression does that too
Seizures, especially in someone who doesn't have a history of seizures - nope
Hearing problems - sometimes one ear will start ringing and loose hearing for no apparent reason, but I think that happens to everyone every now and then...?

I don't want to be blowing this out of proportion or anything, but I certain don't want to miss it if it is something more serious. My cousin had a brain tumor, so I'm a little nervous just because he had one even though they're not hereditary (that I know of). If someone who is knowledgeable in this area wouldn't mind shedding some light on it, I would definitely appreciate it.

Aleve and Advil seem to help sometimes too.

A proper diagnosis of mental health problems involves checking for physical causes, so they can be ruled out.
I would demand a thorough check.
Not to make you worried but in my opinion it's crucial before making a diagnosis.
