Presentation and depression

Today I had to go into Uni for a group presentation on a case study of our choice.
We chose to study Johnny, a 4 yr old who gets on well with peers but isn't developing as fast as the rest of his class. I won't go into details as it's not that interesting.

We all had our areas of research to present as briefly as possible, bearing in mind we had a group of 6 and only a 10 minute presentation. My material has been done since the end of last semester. I prepared one slide with bullet points and wrote myself a script to follow so I could elaborate on those bullet points. Rehearsing at home I think I bored the dog but I could read my slide in one minute, which gave me 30 seconds spare.

My history of presentations hasnt gone well. I get incredibly nervous, my hands and body shake visably, my voice wobbles and I fidget, but I believed today I would be OK as there were 5 other people standing there with me......WRONG!! I was fine until it cam to my turn to talk and as per usual my nerves got the better off me. I could see the lecturer watching me carefully and I hope she understood what I said I really do. I don't want to be marked down for rushing it. My hands shook so badly I couldn't even read my script.

Typically after a presentation is over, people are happy. Its done and dusted with, don't need to worry no more. I came out of that room more depressed than when I went in. Recently, my self confidence hasn't been at an all time high and I've been doubting my ability to succeed in my chosen career. So I came with an alternative. If I can't achieve my chosen career maybe I could lecture in Investigative Psychology. But after today my confidence has hit rock bottom.If I can't talk to 30 people for one minute about Vygotsky's Socio-cultural Theory then how can I talk to 150+ students for 1-2 hours on Investigative Psychology??? How am I going to cope if I ever have to give a presentation at work in the future??? I'm depressed, disappointed and disgusted with myself.,

I believe now might be the time to seek some sort of help with public speaking. There's another presentation this semester in research methods, and I'm dreading it already and hoping it's not an individual one. All I feel like doing now is curling up in a ball under the duvet and balling my eyes out at my pathetic attempt to appear professional. Maybe I should book and appointment with the University Counsellor......
