Taking a break (23f) with boyfriend (26m) but I feel physically sick being away from him after only a weekend

I want to go back so bad, but I’m the one who wanted the break because I feel I need therapy to help my emotional regulation/yelling when we fight
and to get a drivers license (can’t practice on his car because it’s old and he doesn’t think it’s safe, he hates having to drive everywhere like a chauffeur because he’s always been the one to drive friends around.)

My boyfriend and I live together with two cats. He stayed in the apartment and I went to stay with my parents until I get my license and start therapy for a
bit. But now, after just two days away I’m crying all day, been waking up 5 times a night, and feel like my heart is breaking. It feel like the emotions of a break up but we’re only in a break??

I texted him just a second ago saying “I don’t think I can do this break, and that “I’m just anxious that how you feel about me will change while I’m gone.” I
hate that I did this because as my dad said, I need to give him space to miss me, and I need to stop
thinking about him constantly, and live in the now. Why does it feel impossible?

I keep seeing everyone (online) say that breaks are just prolonged breakups and now I feel sick and worried that I’ll never hug and kiss and see the warmth in my boyfriend’s eyes again .

TDLR I (23f) contacted my boyfriend (26m) during our break because I feel like an emotional wreck.
