I conpletely undestand you. I am a college student too!

I know exactly how you feel. Believe me, this FEAR that you won`t do it on time, the thoughts of wat you carp teacher says - prevent you from thinking straigh and doing it right. You can`t sell your self asteem for the low price of having your teacher say this or that. I know how it feels when themn profs, who think they are God or something - talk geeraly - they almost never incourage you! They will scold you with pleasure - but say "thats great you have improved or even ifts not great - all this hard work we are doing - we should give ourselves the encouragment. We should rememeber we have done THE BEST WE COULD and that the Gdolike prof saying " you are rubbish" - this is sad we let it affect it. Cant you ask the teacher not to talk like that? it IS inapproproate!

I remember doign some shittiy Job for my typography design class, and we present in infront of all the class- and he says "are you stable mentally? because i am going to get out on you" and told me that this work would shame a first year student. ( i am on my last)

Talk to her like - politely, in a respectful, calm maner and tell her that thsese expressions - are not haleping but doing exactly the opposite.

I think that your enxiety is a problem. Go to a psych. I know that if anything - this is why you don`t succeed to do all you want. You may not rememebr who you are really - on a deeper spiritual level - and theus not have all the energy and the fun. I see you are not totally a wreck though.
You do things fine.

read The Artsts Way by julia cameron. Great book.
