passionate graphic design student

I am passionate about what i do, i am currently in college pursuing a career in graphic design. In every class the students have to present their work at the beginning of the class, i have being doing it cause i have to, but its not a pleasurable situations as i want it to be, since i am scared to death of public speaking. I believe that i have overcome aspects of this fear, but not completely, i always start to shake and i get really anxious before presentations, but i tend to go through with it. In my head i think i am a good public speaker the only thing is that my mind does not allow me to show that to my class or to the whomever i am speaking to. Thats one of the reasons, the second most annoying and uncomfortable feeling is speaking english as a second language, when i speak face to face to one of my peer or co-workers my accents does not bother me but when i am about to speak to an audience or a group of people my accents kicks in and gets stronger and i know the reason why, because i am really nervous, but i do not know how other people with way stronger accents do it, they are not a shame or at least it does not look like it. Even if i practice my speech over and over when i stand in front and all eyes are on me, i start digging a hole for myself. If anyone has any tips and/or advices i will really REALLY appreciated it.
