Breastfeeding probs

Breastfeeding and pumping. The thing is my third day in the hospital after birth i began pumping and cpuld pump 5 oz from each breast, now two weeks along from babys birth i can only pump from the left 1oz and the other 3 or whatever it decides to give me. I've had a major decrease in milk supply i use to pump enough to store in freezer and have fir the next days now i have to restock fridge after i use one bottle cus thats all im collecting! Baby use to drink 2oz but now demands 3 and im worried i might not be able to breast feed anymore.

I give him breast during day Sometimes nights but if im really tired i pump. But im not the type of person to nurse in public i always carry a bottle or 2 in his bag for when hes hungry , during the period we are away from home. But its beginning to get very hard for me. What should i do, i dont want to give up but its overwhelming feeling like i cant provide it anymore for my son. Its become stressful , how can i increase my milk supply?
