Breastfeeding journey

Hi , I am just 6 months into breastfeeding exclusively pumping and it’s so much mentally stressful for me that I am just taking it day by day and want to continue it to 1 year, even a thought of not breastfeeding gives me so much mom guilt and I feel so bad for my daughter that Even if it’s hardly a bottle a day but it’s still something for her I think to some it would be nothing I know but just for satisfaction I am doing it , I am in a situation where pumping or a thought of not pumping both gives be so much stress and also I am just producing 3-4 ounces a day it’s literally so draining for me 😥🥺 I feel like if I pump I should produce alot more but then also I just pump twice every 24 hours . Please help with tips to increase milk and with encouragement I seriously need that . I have no one around whom I can talk about bcz no one in our family breastfeeds . Help plzzzzz
