Struggling to Get Mental Health Support in the UK

Hi, is there anyone in the uk who has or is currently assessing the adult mental health services please? I really could use some advice if possible please. TRIGGER WARNING - VOICES extremely long story as short as i can get it....... for the last 10 years I have been trying and has my gp to get the mental health services to support me. I have a long list of mental health conditions all diagnosed before the last 10 years. I was seeing a psychiatrist regularly but the service where I live where having a change around so they couldn't see me for 6 months but would see me again afterwards. Well from then on I must have been referred back in well over 150 times from a range of health professionals. But when I very rarely get an assessment from them they just tell me I don't need their help. I have experienced things like my voices gaining control which led to me being unable to take my meds. plus lots and lots more quite serious reasons. I don't want to go to into detail as I don't want to trigger anyone. I am a single parent and my children also have a lot of mental health and physical health conditions. I am also physically disabled so as you can imagine it's not easy. my gp thinks I have cyclothymia and it needs medicating so my moods are more stable. but I need the mental health team to see if they agree and sort out meds. I'm just worried that they will just do the same again and brush it off like it's nothing. I don't understand what I need to do to get some help and support. I have never shouted, sworn or been disrespectful to any of their staff so I just do not understand why this keeps happening. if anyone has any ideas, please could you comment and let me know. thank you so much for reading x
