Please help me get my angels back

I am trying to raise money to get my babies home. My story starts over 40 years ago. I was born and raised into a truly abusive family. Every form of abuse was carried out from a young age. I do not want to concentrate on the abuse as I feel it serves little purpose but there is a need to know so you the reader, can understand why my mental health fully suffered. I was hospitalised from the age of 16 until I was 19 years old due to the severe effect my traumatised childhood had on me. I was later diagnosed as having PTSD . At this point no therapies were available to me. I moved away in my early 20s and much to my joy started a family. My life felt complete,my journey worthwhile. My beautiful baby bundle.All praised my parenting and people often said I was a natural earth mother. When my youngest was 2 years old my father died.I dealt with what I could but buried a lot and continued as at the time I felt I could not deal with it. A few years later it all came to bite me. My past hit me in the face. My whole past roller coastered towards me. I asked to go to hospital and also asked for my children to be cared for before I couldn't. I knew my early warning signs and listened to them for my children's sake. My two eldest went to their fathers and my 2 youngest went into short term restbite. It Broke my heart but was the best for them in the diar situation. At last I was offered therapy ,this was to take a year intensively. I requested for my children to stay where they were for this time and the judge agreed,at this point I could get legal aid with Labour in power. My two youngests foster parents were amazing. My therapy was unbelievably difficult. It took me to hell and back on many occasions. But my babies were always my guiding lights. I also learnt a very hard thing,to love myself. Along the way I learnt many things,some hard,some beautiful. I also learnt I could work and have a part time job which I love. When I was stable and had completed my therapy,I asked for the return of my children. I had to jump through hoops. ( understandably) to prove the strength of my mental health. But thankfully I now have my 2 eldest back with me. However due to the fact my therapy took a year my youngest two babies were put into long term foster care. With conservatives in power I cannot get legal aid and so my two youngest remain in long term foster care as I cannot get legal aid to get it back into court. My youngest twos foster carers have told me over the years my children ask to come back all the time and get very upset. Their foster carers are truly amazing people. But my children want to be with me and their siblings. My heart breaks, I have been stable now for 4 years. I have been told my case will cost 1000s to complete. By the time I saved every penny we have, my children would be adults. I am on this page not to tell a sob story, but to show people can move on from mental health difficulties and because my children want to come home. My other children are with me with no problems and my other two children want to come home. Legalities in court are all that is between my family being complete. I am stable and well and even working now. If my children were settled and wanted to stay where they were, I would honour that however hard for myself. But they truly want us all back together. I could go on and on but I think I have got enough down. At no point was I called a bad mom, life just happened. My children want to come home. There is no reasons why they cannot come home. Please help if you can,thank you with all my heart. Thank you for taking the time to read this and helping to get my angels back♡
