Wow, I’m so so sorry that you are going through this. I can only imagine the level of pain you are experiencing right now, but I want you to know that you will be okay. I promise ❤️
If I may suggest three really wonderful books that you may find beneficial:
How to Survive the Loss of a Love (personal favorite)
Take this time to allow yourself to grieve, and I mean truly allow yourself to feel all of your emotions as they come. Continue to work on bettering yourself and healing your broken heart. Get involved with friends and family, explore new hobbies, and lean on God and His word! I know it feels like your whole world is crumbling around you, and you aren’t sure if you’ll ever feel happiness, let alone love, again but you will.
