Am I mentally ill?

I fall in love with people so fast. I’ve been talking to this guy for about a month and a half. He’s all I think about & all I want to be around. I’m usually not the clingy type but with him I want to be. I hate when we aren’t talking, aren’t together and I obsess over the future with this man. I just feel like it’s too soon to be feeling these feelings already and I’m terrified of being hurt but the feelings are already there and I can’t deny it. Literally in the usher song “you got it bad” rn. 😂 is this normal for others? Or do I just fall in love just bc someone likes me back. Lmfao
