Does it make me a crappy mom if I stop pumping? (lots of difficulties breast feeding)

My son is 1 month old. I cannot breast feed because I have really small nipples (he can't latch well) and also a very fast let down (if he latches after a long time of trying he starts choking and unlatches). I tried nipple shields and he hates it and talked to a lactation consultant and I'm just at a loss. I really wanted to breast feed. I only pump now and its inconvenient. My son doesn't give me time to pump so I miss sessions and my supply is going low and waking up at night to pump is depressing and exhausting. It's just making me crazy thinking about it. I want to stop pumping and making milk for my own sanity but is it wrong of me to deprive my baby of breast milk? I don't know what to do. Can anyone offer me some advice? Thank you..
