Struggling with words and communication

I haven’t always had the most extensive vocabulary but when I’m in a depressive episode my ability to communicate and articulate myself suffers significantly. I lose my natural diction and I don’t have words to adequately express my thoughts. This affects any social interaction I have, and at work oh man the frustration and defeat when not being able to explain simple concepts is..embarrassing to say the least. I feel so dumb.

For context, I’m not on medication so this isn’t a side effect. Just want to clarify since I’ve read on here that some have experienced a loss of access to their “word bank” when taking medication.

Wondering if getting on medication would have a reverse effect, I don’t know. I’m getting desperate. Please help if anyone experienced this and found what has helped them.
