I was diagnosed with social anxiety , ptsd , and bipolar can you experience day to day memory issues ( can't remember what was said 5 minutes before ) 247 500 million thoughts running through my head?

Your emotional state can compromise cognitive function, and also compromise sleep, which also could affect memory. But, could also possess metabolic problem such as low thyroid function, or vitamin deficiency, or medication reaction, and these factors may be causative. Have a psychiatrist evaluate all of this. Psychological testing may be useful.
