Mature Returning Student

Hi I have some questions about options.
I want to return to university studies but I don't know if i can get student finance. I have used 3 years of funding from retrying years of study due to personal reasons and then i have been out of education for 3 years?
I dont really know what to do if i cant get SfE either if you know what i can do there either? I really need to do university and i have no idea what to do around finance. i made stupid decisions when i was younger because i had pretty much no guidance and i dont know what i can do if that ruins my life

I would like to study a full-time course if possible. I did not gain any qualifications from previous study.

Thanks

Ah sorry! Looking to do Chemistry bachelors or masters, with a Foundation year if needed as i've not been in education for a while. its Chemistry, Pharmaceutical Chemistry or Chemical Engineering as the three kind of hot subjects id want to apply for. I will also be limiting really to the Man Met uni, Uni of Manc and Uni of Salford if that info helps. Thank you for taking the time to answer this query!
