I can reassure you that that feeling of overwhelming grief at the future you envisioned for yourself will fade someday soon. I had so many plans for a summer filled with dates and sex and laughter. It was devastating to lose that future, but after about 6 weeks, I began readjusting. Not that the rest still doesn't hurt...
Honestly, I truly hope that things turn around. Drastically. I hope that you both get what you want from this. I am so hoping to see someone "make it." I'll hold on to that possibility for you so you can put your energy wherever it needs to be right now. <3
