Home button

I’ve had my SE 2nd gen for 3 years now and today i’m not sure what happened but my home button has been different. It’s hard to explain but it’s extremely sensitive and just running my finger over it a little makes it double click & it makes it really difficult to use my fingerprint to sign in. It didn’t make a noise before at least not as loud as it is now and i can actually press it down. I think it’s broken somehow i just don’t know i couldn’t find anything about this online. It’s just really annoying cause everytime i open my lock screen to sign in it immediately opens my apple wallet. I just wanna know if anyone has ever dealt with something similar & we’re able to fix it.
