No advice really but just to say that I hope the situation improves for you. It can't be easy at all. You are doing an amazing job raising a baby. I have huge respect for single mums. Sending you love. X
I had my first at 20 and it's HARD. I did live away from home but was also a single mum. Firstly, I'd encourage you to speak to the health visitor about your mental health and get some support through counselling. You're still within the 1st year so you should be prioritised. Secondly, are you working? Are you on maternity? It would be a good idea to start saving to move out or seeing what support there is to move out. Family should help and support you but if they're anything like mine, they aren't that supportive or helpful. Relationships may improve once you move out. Priority though is to speak to HV or GP and get some support and see what is on offer and available x
Granted you chose to have a baby but I'd like to think that family would be supportive regardless... Are you able to get a letter from them to say that they are making you homeless? Are you financially stable enough to move out and support your baby? I had my little boy while still living with my mum so we were in 1 room and the kitchen/living room full of baby stuff, to some people it looks like mess but it isn't... We recently moved out and now my mum feels like it's a privilege to see my LB, message me if you need a chat xx
