I need some advice please

I have been struggling with psychosomatic symptoms my whole life. I've had a bunch of tests done but everything was completely normal.So we found out its psychosomatic. Lately its been getting worse almost everyday i get the symptoms like I feel very dizzy cant even walk straight and tired to the point i cant even hold my head up or i feel like throwing up i threw up twice from it.I also shake a lot and breathe quickly i also used to go use the bathroom like every 20mins it was horrible at school.Thankfully i don't have that anymore but the rest is really botherering me i have my psychiatrist appointment all the way in january we'll try to think of something there. But please give me your advice if something worked for you tell me.thanks
