Just had a presentation in my college class. Felt, and still feeling, very overwhelmed and anxious. Any tips to keep my cool? This was a super basic 4 slide powerpoint presentation in front of 15 or so people but leading up to the presentation I got that pit in my stomach and I started to freak myself out. This has been happening my entire life and I hate it. During the presentation, my voice was (from my point of view) very shaky and almost felt lightheaded. Any ideas of how I can keep this from happening?
