Looking for SDR role in Europe

M27, Italian, finance background, I’m looking for SDR role in Europe, I’ve already one year of experience selling financial products. I keep receiving rejections and I’m finding really hard to land a role in this field. Do you have any advice? I’m really motivated to learn and confident that I could be a great fit in sales but I just need an opportunity to prove it.
I would appreciate any help you can give me
Thank you
