clingy or too clingy? is this normal

Love.peace.happiness
Is it normal to basically have withdrawals symptoms from not being around or texting my boyfriend, he hasn't texted me in a couple hours but I feel like Im mourning a lost of somebody  like I want to cry, I'm snapping at everybody, and I'm blowing up his phone. I sound crazy but it's true, is this normal😭😭😭??? I miss him so much and I saw him yesterday
