Thanks for your question. My name is XXXXX XXXXX I'd like to help you out.
I'm sorry to hear about what you're going through with these problems with your memory. It does sound like a very frustrating situation. From what you've described there are a couple things that could be contributing to this problem.
Anxiety and stress
are one of the most common reasons for problems with memory. If this is the case in your situation, then it would make sense that during particularly high periods of stress, such as an argument or heated discussion, that this would make it even more difficult for you to recall and remember things. In terms of overcoming this, it may help to consider when this problem got worse for you, and whether it coincides with any major changes in your life or sources of stress so that you can start to resolve those issues. It is good that you are on medication to manage your anxiety, but it is also important that you are also working on this problem in counselling or taking additional measures to resolve your anxiety on your own so that it starts to improve and you are not dependant on the medication. In most cases, once your anxiety levels improve, you will start to find a drastic improvement in your memory.
Another possibility is that your anxiety medication is having an effect on your memory. This is a common side effect of some anxiety medications, and you may find that with a medication adjustment of your dosage or the type of medication, that you see a big difference in your memory. Again, think back to when this problem started. If it started to get worse around the same time that you started the medication, it's certainly possible that there is a connection there. Knowing that, it would be important to meet with the person who prescribed the medication for you so that you can discuss this with them.
After reading your question, those would generally be the most common reasons that you would experience this problem. It's easy to feel like you are losing your mind when this happens, but most people find that their memory returns once they have a better handle on their anxiety and medication. I definitely wish you the best with all of this, and if there's anything else I can do to help just let me know.
