Helllo! Hearing your situation really tugged at my heart strings. There isn't much worse than feeling a swarm of negative energy around you on top of your own inner turmoil like you are experiencing with your ex. :( I'm really sorry to hear someone would say such mean things to you about the things you have gone through. It sounds as if your ex is not really being supportive of you, but you are deserving of love, understanding, and compassion whether he sees that or not. Don't let the opinions and hurtful remarks (about the rape or miscarriage) that people impose on you affect you. You have every right to need to deal with those things and to feel your feelings before letting them go, otherwise, proper healing would not occur.
The best thing you can do for yourself is find things that are uplifting to you, and seek out the company of those who will seek to understand and cherish you.

You deserve it!
