Restarting life , advice?

Hello , I hope all is well.

I am a 23yo woman who has left an abusive household / relationship after saving up a little chunk of money and a big fiasco after finally pushing me to just leave. It took me a while to be honest to understand there wasn’t really anything there in the relationship and he would never change, I was clinging on to a change embarrassingly and felt constant guilt.

I’m currently booked into a cheap hostel but I’m wanting to arrange to live somewhere cheap by renting a room out monthly so I can start looking for work but this is a little hard since many places require you to already be working etc.

I’m just wondering if anyone has possible went through a situation like this and has advice on what I should be doing? Like the best way to save money , make money while jobless and I’m also wondering if anyone knows cheap places to look for room to rent , what the whole process is I’m a completely clueless person when it comes to understanding all of this and it makes me extremely overwhelmed when I try to look into it , which I know is a pathetic excuse but it’s honestly like my brain flips off and I can’t read the words on the screen anymore whenever I try to do stuff like this I just get stressed out and blank it’s embarrassing because I’m in such a bad situation right now. I’m trying to push myself but I’m just a bit unsure about certain things.

Anyways I’m just wondering basically if anyone has advice on where is the safest most affordable place to rent a room out in Ireland right now anywhere at all and what to do for money while I’m looking for a job. I can’t go on the dole because I don’t have documents they need due to homelessness for a year and a half now (I left my abusive household after a very serious fight involving guards and was extremely vulnerable and stupid very much thinking my abusive ex was going to change due to the serious events and step up to be a team but he would get into constant fights or drink and abuse me I know I’m stupid for thinking a change would happen) and not having access to certain things needed. I’m in the middle of trying to sort this out now also but in the meantime I need to start building up money because I’ve spent a good chunk on clothes , the accom and food.

Just any advice or a point in any direction would be really appreciated even little things I’m just not sure if I’m doing the right things and just wasting a lot of money. Sorry for the huge rant and I know a lot of this is my own fault which is why I want to complete start fresh all together and get my life the way I want it.

I don’t do drugs im extremely against it I barely drink only occasions and I don’t get black out drunk. I’m a quiet person I’m extremely shy and antisocial I’m very clean I’ve worked as a cleaner majority of the time. I just need a chance and I know I have one right now so I don’t want to fuck it up.
