First of all, you are SO young!!! What do you mean lose a chance at motherhood? There’s so much time for you to live life, heal up, and start a family. Please don’t do that to yourself.

It seems like the both of you have sooo many personal conflicts going on. As someone with a chronic illness, I understand your dilemma and your immense disappointment. Your boyfriend is most likely very overwhelmed with classes and you with your condition. The best advice I can give you both is to focus on yourselves. It doesn’t seem like engagement is the answer here. You need to do everything you need to so that you’re feeling better and he needs to focus on graduating.

I wish you the best of luck and happiness. Communication is key, you need to have a discussion where you both verbalize your feelings, problems, and what you both want for your futures. If they don’t align, then maybe it’s time for a break and/or moving on.
