Bipolar disorder has many parts to it. It can cause almost any kind of mental symptom. Therefore, "emotional confusion" and "numbness" are possible symptoms. But they are not typical of bipolar disorder.

Bipolar disorder used to be called “manic-depressive disorder.” People with this illness have wide mood swings. The down side is depression. The up side is called mania. 

During mania, a person becomes very active, but in a scattered and unproductive way. He or she may be full of energy. Or may get irritable. Or may sleep very little.

Speech and thoughts can speed up. It may be easy to get distracted.  

During mania, behavior can get reckless or embarrassing. Spending too much money. Making bad decisions about sexuality. Or dreaming up grand plans that could never be carried out. 

Sometimes thinking gets terribly distorted. Psychotic symptoms may develop. The person may develop false beliefs (delusions) or false perceptions (hallucinations).

Most people who have manic episodes also experience periods of depression. Symptoms can include:

• Loss of interest in things they previously enjoyed
• Trouble finding pleasure in any activities
• Low energy and feeling tired much of the time
• Difficulty concentrating
• Thoughts of death and risk of suicide

Back to your symptoms. Confusion can happen if your thoughts are racing or distorted. Numbness can be part of depression, for example, if it’s difficult to feel pleasure.

But it would probably not be bipolar disorder if you only had those two symptoms.

Nonetheless, these sound like distressing symptoms to me.

You don't need an official diagnosis to get help. Talk to your doctor or a counselor at school. There are many good and helpful ways to feel better, whatever the diagnosis.
