I think it started after college and I am almost 29 now. I have had depression and my memory retention was really bad during this phase. I started getting treatment and therapy for it nearly 1 year ago. I think I have always been kind of oblivious at times, but now it seems like I need to use repetition tricks remember important things. I'm not a vegetarian, smoker, drinker, and exercise at least weekly. It could be bad sleep hygiene, but I'll definitely check out B12 and thyroid problems. Thanks!
