Weak episodic memory recall. Treatment.

I am a 24 year old male. My main problem is my memory. I don't seem to remember things which others do easily. Like my friends easily can remember a movie dialogue, or a situation or what someone said in a particular situation. I always struggle with getting the context, and to focus. This makes it very difficult for me to get along in social life. This problem hasn't started all of a sudden. I do not know for sure when it did or it was present from my childhood. I have tried ADHD(stimulants) drugs, but they increase my anxiety; Escitalopram makes me feel much better and sociable, but I do not like the long term side effects it might have ( erectile dysfunction ). I excercise daily, it makes me feel better but doesn't solve the problem entirely. My TSH , haemoglobin levels are within normal range, My diet consists of non veg, and thus I do not think I have vitamin B deficiency. I do not have any allergies and my blood pressure is on the lower side normally. Please suggest a treatment.
