I can sense your frustration with all the rush of emotions that you're so overwhelmed. May I please ask why you guys ended the relationship in the first place? Getting over any type of lost is very difficult for anybody so you're not alone in this. But maybe by focusing on the more positive things from this situation can help you take little steps from letting go and accepting things for what they are. People come and go for a reason and some stay longer or shorter than others in our lives but they are all there to teach us something about ourselves. Thats good that you're being resourceful and taking care of yourself by taking your meds and working out and stay focus on that you're doing great. Do you have a good friend by your side that you can call when you have your weak moments when you just feel so overwhelmed? How about taking a stroll through a park or what helps me is to go to the mall and be in the company of others and sit at a cafe with a good magazine. Keep writing to all of us its a great way to release your emotions.
