This may not directly answer your question, but reading it I went "Ouch!", so some advice...
I think it's important you remember that applying for a visa is not like applying for a passport. It's not just a matter of filling out an application form and providing the required documents, and that's it, you get it.
It's more like applying for a loan, or trying to get a job, or applying for a top university. You have to convince them it's a good idea for them to give you a visa.
Visas are not a right. Countries get to pick who they want to let in or not, and they mostly want to be sure that:
That's why they ask all those questions. Their goal is to ascertain:
For the first point, you're saying you don't have a job, so that takes out the best reason. You need to have a good reason to return home, otherwise your visa will be denied.
For the second point, since you apparently don't have any income, how are you paying for the trip? Or who is? If someone else is paying for it, you need to provide details for their financial situation.
Also, you state that "Sometimes my mum sends money into my account to hold it for her which is like 10 times what I normally spend". This is a huge red flag, as it can be considered "funds parking". They like to see regular, consistent income, not irregular deposits.
I strongly recommend you read this answer and this one.
A majority of your outgoings should be quite consistent: rent, utilities, food... Is that not the case? Are you still living with your parents maybe?
You really need to paint a picture that shows it's in the UK's interest to let you in. Sure, if you're the heir of a (non-Russian) gazillionaire they probably don't care about your income or your outgoings or anything at all. But if you're just an average person, you need to show that you match their requirements, and pay attention to all the red flags (and there are many in your case).
Also remember that if you're not sure your application is good enough, you probably shouldn't submit it. It's not like "I'll submit this and see what gives, and if they say no I'll retry a bit later". They have a memory, and first impressions last. Once you have a rejection, they will look at further applications with even more of a suspicious eye than a first application.
And finally, remember that some countries will ask for visa refusals from any other country, so it won't be a problem just for the UK, it may prevent you from getting visas from other countries as well.
