What do you mean by clingy?
Do you mean possessive and controlling? There is a fine line between healthy and consensual and unhealthy, in my opinion.
Do you mean you just need a lot of emotional support, cuddles, hugs, kisses, and texts/communication? That's probably okay, but you should, of course, listen to your partner in case they feel too overwhelmed.
If you truly feel like it's "too much" then it might very well be too much. Be realistic with yourself.
I wholeheartedly believe that there is a healthy, happy match for every person inside and outside of our shared interest here.
You just be perfectly you.
