Anyone else experiencing really frequent mood swings?

It's got me feeling super confused on if it's another disorder or just my autism , I can go from being happy one moment to being really sad , or being angry for no reason , but alot of the time I can't recognise what emotion I'm feeling so I'm just numb inside and don't know what to do. It affects me alot but I don't express it to anyone as I don't have people that'll understand.

So just curious if this is an occurrence anyone else experiences?
