Side effects - Will seroquel cause a cowardice feeling?

[Yeww]

I take seroquel and prozac but prozac is the least likely suspect.It seems that from the starting day I took them I always have a kind of frightened feeling to give opinions to people or have dicussion or voice out a disagreement on the way a university project is done.Even after graduation and into a different environment,I still feel that way.

There isn't any other way to overcome this but I notice that on days when I have woke up after sleeping for 11 hours,I most likely do not feel afraid.Rightfully it is illogical that sleeping too much will make you feel braver so I think the combination of prozac and seroquel could be the cause.
40 minutes after taking the combination I feel thirsty and will have a knockout sleepy feeling.So on my guess,it could be that sleeping for 11 hours helps because the effect has worn off.But on days where I have to attend university I sleep for only 5 hours so the effect has not worn off and causes a cowardice feeling

Any thoughts on it?
