I really want to go to UEA but currently have an offer from Birkbeck

This will be quite long to read and apologies if it sounds really dramatic but I am just depressed now.

I really wanted to apply to East Anglia for history with a foundation year, but currently I have offers to study Law at Birkbeck as my firm (Hertfordshire as insurance).

My question is will I be able to apply through clearing to UEA even whilst holding an offer?

I really have made many mistakes this year, I am currently a gap year student with no prior money saved for university. The main reason being is that I retook A-level exams - Psychology and Economics ( I currently have a B in A-level English language). Due to extenuating circumstances both last year and unfortunately this year I don't think I performed to the best of my abilities (my target grades are BBB and the course requirements are CCC). The extenuating circumstances were that I suffered heavy domestic violence and constant emotional abuse from my father which rendered me completely unstable and unable to efficiently study for my exams. I understand that people may suggest that me wanting to go to UEA would be seen as just a getaway from my father, and while that is somewhat true to an extent, my main reason is that I feel I can grow better academically at East Anglia and I have researched the subject content of the course that I want to do and am very keen to study it. I feel that it will equip me with necessary skills and open a wide pathway of career options, nevertheless I am quite fond of the subject.

It will be a huge gamble for me if I request that both Birkbeck and Hertfordshire reject me, and at the same time they may even refuse to reject me which adds to my stress.

Also if I do somehow luckily manage to gain an offer from East Anglia I have a bundle of other stress to deal with such as student finance, accommodation and also how to explain to them that I wish to study history with them when on my personal statement it strongly suggests that I wish to study law. Although, I do feel that History would be more beneficial for me to study which could eventually levy me into taking Law as I'm aware that many Lawyers have not actually graduated with a law degree but with a variety of other degrees then undergone a law conversion course.

Sorry for the long post, I've been crying for so long because of all the stress that I'm just so lost and in need of guidance.

I've seen that they have that course in clearing now (hopefully it will remain in clearing after results day), I'm so stressed out that I will be rejected by them and have no offer this year

Thanks, also in terms of finance if I am somehow able to get a place, will I survive without any money saved up? What would I need to do beforehand, I'm quite ignorant in the fact that I have no idea how accomodation works, is there some kind of deposit pay?
