How careful do I need to be with nut allergies?

Ok, I just found out I may have nut allergies, and i need some help from people with experience. I Feel like a leper right now, how do I stop being so afriad of EVERYTHING! Everytime I eat I get a panic attack and think that im ognna get an allergic reaction, Im scared to touch anything ot anyone for fear that nuts may have some into contact with it, and when I eat, im afraid I will accidentally ingest an ingredient I didnt know had nuts or didnt lable it was made in the same place with nuts! Please help me, what CAN I eat??! what is safe and what is not? My dr. said that the allergy scratch test didnt show it was serious, but hes gonna do the blood test to be sure, but in the mean time im a nearvous wreck! Please help!
