Help? Weaning?

[Skywalker]

Hi, I have a 3 month old and I'm sorry to say I'm already considering weaning him onto formula. I have recurrent clogged ducts, milk blisters, and issues keeping my blood sugar and hydration levels up even though I do try my best to eat and drink enough. I'm not getting enough sleep and I also have an anal fissure which is continually being reinjured every time I have a bowel movement, so sitting for 40 minutes every 2 to 2.5 hours to breastfeed is incredibly painful. I'm going to be going back to college and doing an online degree but 20% of it is on campus. I don't do well with pumping breastmilk and don't seem to get a lot of milk out when I do pump, even though I produce more than enough milk when I feed him directly from the breast, so pumping just doesn't seem the same as breast feeding. I feel like I'm going crazy and I have very mixed feelings about doing this, but I'm not getting enough sleep and I am a single mama, have been since the second trimester of my pregnancy and it's 100% go-time for me all the time. I don't have another person around, so I'm the one constantly having to do everything, and since I run the risk of getting painful clogged ducts which take agonizing DAYS to correct if I don't feed him at least every 3 hours, even though he sleeps sometimes for 5-7 hour stretches, I have to wake him up to feed, whereas if he was being formula fed, we could both be sleeping during those stretches.

How do I do it? I don't necessarily want to take more than a month to do it and I know that might be fast, but I'm just feeling desperate at the moment. It's so freaking hard for me because I wanted to breastfeed up to one year but I don't think that's do-able for me. I didn't forsee all of these challenges. We also use a breast shield because he's never been able to latch without one, no matter which lactation consultant we saw (he had a minor tongue tie at birth that was so minor the specialist we saw at the hospital didn't want to snip it and I had flat nipples) So I'd just like to not have all this physical and emotional stress for either of us anymore and could really use some advice please!
