stopping Breastfeeding.

I haven't had a very easy BFing journey. I get vasospasm so was only able to do 2 BFs a day. I've had to pump since my baby was born which has been hard work. Baby is almost 5 months and my supply is almost gone. I'm feeling very emotional and sad about it and will cry because I just wish I was able to produce more. I had oversupply for many months, had a really large stash in the freezer but then found out baby was dairy/soy protein intolerant so had to donate the stash I had. I always aimed for 6 months. I know I'm being hard on myself but I just can't shake the guilt I'm feeling. :(
