Im just wandering what everyone on here recommends to dealing with stress adn anxiety...I have terrible SOCIAL SHYNESS and anxiety and dont know what to do.

Im taking fish ols and GABA with Niacinamide and B6 and INOSITOL.
MAGNESIUM CITRATE ( This stuff isnt very good it makes me feel distant or strange.

Im looking into VALERIAN (Tried it before but made me more strange or stressed).

Maybe Phosphatylserine have took choline but made me worse as did B VITAMINS which make me paranoid.

I have internal jitters or tremors and SO much tension in my stomach I cant relax and posutre is wrecked so maybe im not breathing....

And breathing techniques are stupid...I dont know which one to beleive..I have been doing stomach breathing for monthes and now my stomach muscles are WEIRD and pushed out from the breathing exercises.

My stomach feels like a weight.

I dont know what to do and I have a 40 minute PRESENTATION in front of the class on tuesday and I am so nervous because I cant even talk to people normally without getting MOODY or anxious so how do I speak in front of MANY
