Thyroid dysfunction causing the depression?!

I was reading some posts in a forum which is supposed to provide further help for depressed people. Reading the story of someone, who had a simple thyroid dysfunction which was never diagnosed made me think about that.

And so I ended up doing some research hanging in front of my laptop tired as fuck and feeling like a zombie. I could not believe what I found, because it was a possible disease that causes the depression besides my tough childhood.

I checked the following symptoms that come as potential symptoms for a hyperthyreosis:

- Loss of weight (No chance to gain any weight through eating a lot or/and training)
- nervousness
- diarrhea (similar symptoms like irritable colon)
- difficulty in concentration
- tiredness (also after long hours of sleep [10 or more])
- insomnia (sometimes problems to fall asleep)
- shaking (sometimes I can't execute a accurate movement with my hands)
- mood changes
- helplessness (feeling like I am lost)
- muscle weakness (I feel very weak, but fortunately I have no muscle pains)
- eyestrain (feels tired, burning and itching)


I am male 22 years old and I have family members with thyroid disfunctions (mother, aunt, grandmother). When I started the treatment (which I canceled) in Germany there was no checkup of my organs to ensure it is not caused by something physical.

On the last Thursday I had a appointment with a family doctor, where my blood was tested. I had the results very fast on the next Monday (surprisingly). 

Looking up this strange unknown abbreviations for blood values I found out that ATL a liver enzyme is out of the range, but talking with the assistant I was told that I might have problems with my kidneys. Now I need to wait 3 months to take another blood test.

Time passes, but at least I was able to take action...
