I am glad your feeling better. The fact that you have 2 more blasts left means you have two more chances. I am so glad you can see the posisitve in that Thats something to be so grateful for. Blaming yourself is so easy to do, but the fact is, IT REALLY ISNT YOUR FAULT.
There is no fault in matters of infertility unless your doing drugs or drinking like a fish or something stupid like that. I imagine you know this but just need to hear it from someome else 
I dont know why IVF works sometimes and other times it doesnt, and I dont know why some woman are so fertile and others like all of us have been so challenged. But I do really belive in a never give-up attitiude for something you really want. And I belive you and your DH have what it takes to make your dreams a reality. If you didnt you wouldnt be on this board and you wouldnt have tried IVF. You are a rockstar and you can and will have a baby. Your have to belive that to your core because that is half the battle. Now I dont want to sound like I am preaching or anything, but Heres what I THINK I would do If I were you at this momnet. And this is what I did before we started IVF. Its just my humble opinion but its not to insinuate you didnt do this stuff or did something wrong or that by doing any of this will improve your outcome. I am simply sharing my personal thoughts.....I also dont know your complete IVF history so please keep that in mind-I would sit down with my Dh and go over all our finances and come up with a plan on how many rounds of IVF we were willing to agree to do if at all possible. (That was the case for us, we planned for three, and if we had to try beyond that we would talk about it then) I think the reason we did this was because we needed a plan and that helped us for some reason. If we failed the first time, which for my age was very much statistically probable, we knew we had two more trys and possibly some frosties.
-I would look at my diet and lifestyle and see if there are any things I and my DH could do that may improve the outcome no matter how insignifigant the changes may seem. Both mysllef and DH were on supplements and really healthy unprocessed eating. Now I am not insinuating that your diet is bad or you did or ate anything wrong, so please dont take it that way. Changing diet is so hard for allot of us. Its something my DH & I did and I believe to my core it really helped. But thats just my personal feelings. We went over the top about it though, I really studied ferility nutrition and read a ton of books and took the best from each book I read. And DH was on baord luckily and did it because he really wanted to do what ever it took.
I would take a break for 1-3 months beetween each cycle if depending on your age. I would want to give my body a break from the drugs, the stress and build up my self esteem and courgae to face the music again. Since your doing FET I guess you need less time, and no drugs? So I guess in your case doing FET its differant than a full IVF cycle. I wanted to do fresh cycles and only use frosties as a last resort simply because of my age. But your younger I think??? Not sure. I have read that FET can have higher success in some clinics but in others not so much. So I am not sure about any of that. I have read that fresh is best and I have read frozen is better in some cases too.
I just want you to know I am so sorry. I know when I suffered my m/c's no one could comfort me and it was something I had to work through for myslef. I imagine its the same for you and others who had an unsuccessful cycle or FET. But when all is said and done all we can ever do is push forward, pick oursleves up and get on that train again and keep trying until we cant try no more. I wish I could find the perfect words to make your pain go away...but I am sending you a huge cyber hug. There were a few times I felt like giving up, and I did for a little while I have to admit. DH & I tried for 9 years and I really didnt want to do IVF..........but I am so glad we did & I didnt give up....
I don't think we get refunded for anything. I guess the reasoning is that it's not their fault either that you didn't have a response or had a cyst and they did put the work into your visits and and "cycle management". They shouldn't charge for an actual retrieval or transfer if it doesn't take place. But a cycle management fee and all the visits fees would definitely have to be paid. Shouldn't be $2000, though. The ER and ET is where the big bucks are.
. So really, that's not it either. There could really be the whole natural thing of "it just didn't work out this time". It's not like people that don't have fertility problems get pregnant every time they have unprotected sex around ovulation (except for the Soap Opera one night stands, natch). So maybe, it just wasn't right this time.
