Try to imagine the pro 's regarding the breakup: less stress and anxiety? More time to do what you want? No one to interfere with how you want to raise your child? I know this is hard, but you have to open up alternative neurotransmitters in your brain. If you are stuck in the "this sucks" mindset, it will take a lot longer to get over it. And remember that depression is one grieving process step away from acceptance. You will never forget your love, but perhaps you can accept the situation.
