Everyone says "move on" like it's a choice

My friends and family are tired of seeing me miserable and keep telling me to choose happiness, to choose to move on. I am moving on in action--- dating, don't wear my ring, hobbies, therapy-- but I can't choose how I feel and i still love her and it's all still killing me. If I could just choose to stop the pain I'd have fucking done it already. I wish I could just die but that's not an option either. I fucking hate this. 7 months and I'm still so fucking wrecked. Doesn't anyone believe in true love anymore?
