Last Night I Had A Very Scary Episode. I Am

Last night I had a very scary episode. I am recovering from anorexia but did eat okay yesterday. I was walking into my bedroom told my husband I didn't feel well. I felt off didn't know if I had to vomit had dry heaves. The room was spinning took my sweatshirt off soaked in sweat losrt balance everything went dark I passed out on floor. Laid on bed had few drinks of juice do not remember anything else woke up this morning. Both my husband and I were terrified of this episode. Today feel so cold and drained.
