Is this normal?

If I get in a bad fight with my boyfriend I usually cry. During this time I feel like it's the end of the relationship, I feel like I just need to call it quits and move on. I feel like we aren't going to work out and we just need to stop wasting time. But then when we talk about it and make up I feel the complete opposite, and I am so glad I didn't act on my crazy emotions. I'm wondering if it's normal to get a little crazy when you're emotional and crying 🤷🏼‍♀️. Or if I'm just blinded by love when we're not fighting.
