When experiencing stress related loss of appetite should you force yourself to eat or simply wait for the desire to return?

I have what seems to be an intense adrenergic response to dating. To combat this I have tried taking L-Theanine and Pregnenolone, neither has helped at all.

My pulse rises and stays above 100 leading up to and during the date, my limbs go cold, I shake, I am unable to loosen up and be myself and I feel this is leading to me struggling to build genuine connections.

I saw a girl I dated a few years back last night who I’ve always liked, I feel a strong love-sick/ cortisol filled feeling since seeing her.

Any advice to help me get this under control and improve my ability to stay calm in these situations?

I am otherwise calm and relaxed.
