It doesn't hurt to talk to your doctor about an increase in the medication, and about other things they might suggest to get you through this difficult time. Do you have someone to talk to right now (ie a counselor)? Someone who is supportive and impartial and can help you process?

My last relationship (ended up being 6 1/2 years) I vowed that if it ended I would never be with anyone again. Well, it ended. And I was broken. We tried being friends for a year and finally broke it off for good. We continued trying to be friends but eventually I broke it off for good. I had to walk away and put him behind me.

Now I'm with someone else and she's amazing. We're engaged. I took a four year break in between the two of them and it was exactly what I needed. I'm not saying your situation is anything like mine, or that you need a four year break. I'm just saying (as you may already know) that over time you will feel better about it, and it's okay if you don't right now.
