Tell me about a career as a photographer in London

I’m an immigrant in London and I don’t own any property, nor do I have any savings or parents to support me. So I need a steady job to pay my rent and cover my living expenses. I currently work full-time as a product photographer and manage the company’s online shop and various online marketplaces. It’s routine, but straightforward and enjoyable work, though it doesn’t pay particularly well. My only problem is that I don’t yet see a path forward to continue living in London. I have very good technical skills in photography and it’s no problem at all for me to get to grips with any equipment. But I’d like to try other types of photography in my spare time, such as portraiture and other more creative photography. Could you advise me on how you got started, for example? Is there any point in staying on as a photographer in London? I enjoy it and I can handle the routine of editing images, and I also have good soft skills when it comes to communicating with people. I just need some advice right now, because I feel a bit stuck and have lost confidence in myself. Thanks!
