I'm torn...

I have been breastfeeding since baby was born 12 days today. I am Bf once or twice a day but I am pumping and producing 2oz per breast in the morning and about 1oz per breast/pump for the rest of the feeds. I supplement every once in a while. I'm trying my best to save up my milk but have yet to have enough to freeze. I want to keep pumping and BF for the benefit of the baby and I love knowing that I am providing food for him, but at the same time I feel like it has totally consumed my life... I feel so selfish. When I think of stopping to try to get my life back a little bit, I cry and feel so bad. When i think of continuing, I feel depressed... anyone else feel the same? If so, what's a good way to cope?
