My girlfriend is too clingy?

I've been dating my girlfriend for 3 years and living together for 15 months. She's very clingy, constantly calling and texting, and gets irritated if I don't respond quickly. She dislikes me spending time alone, seeing friends, or visiting my family, and she gets upset if I do anything without her. Her overbearing behavior makes me feel trapped and unable to have personal freedom, turning our home into a prison. Is this level of clinginess normal, or am I overreacting?
