is there any where in Wales/UK that helps with vulnerable people and paying off loans?

First of all this is not a post to gain benefit from others I just need some help to know where to go to help myself. 

About two years ago I was in a legal battle with my ex partner to get my name on my daughters birth certificate and be a part of her life but now i am in a position where i am paying over £350 a month repaying loans that i simply cant afford since losing my job and being made unable to work last year because of how bad my mental health had gotten. 

I thought i'd ask here as im at a point where i dont know where else to turn to and i feel like the people of the internet might have more information on this topic. 

Its a long shot but id appreciate any help that you can give!
