If you genuinely have to ask, the answer is likely yes.
Gaslighting isn’t simply disagreeing or lying. It intends to break the target’s trust in their own perceptions. That’s the hallmark, no matter who does it or how. Especially if they gently assure you everything will be fine: it’s just that you’re a little too emotional and don’t understand how to think like logical people do.
And yet… by the time you’ve been immersed in it for a while, it really does feel like it’s your fault, that you’re forgetful or clueless or just can’t understand real life. That’s their whole point.
So is it really just you? Check in with a therapist or social worker if you can, because you probably really do need help: not because there’s anything wrong with your brain, but because resolving or extracting yourself from such a situation is hard. They can help you find support.
