Suffering Severe denial

relationship of 4 years and she broke up with me over text because she says we’re very different and arent meant but deep down i knew we werent that different and we were compatible she had mentioned this a lot before and i had tried and tried and tried to fix it and be what she wanted but i guess it never worked now im stuck in a state of denial where throughout the day i feel ok bc i think shes still there. I feel like shes still there but we arent texting because shes just at work, then I realize thats not the case and i struggle greatly please anyone if you can help me I need help
