Sleep

So we are currently waiting for assessment for our 7 nearly 8 Yr old daughter we have waited so long for this 

Bit of back story 

Suspect she was autistic since starting school kept asking school and basically got made to feel like I was stupid moved her schools and within 3 months they approached me telling me that they think she could be bearing In mind we moved end of Sept 20 they had lockdown and bubble collapse so half the time wasn't in school

Any way 

We are STRUGGLING we feel like she is manipulating us 

Bedtime is a nightmare she has to have lights on a fan on won't stay in her room and even has one of us sleeping on a mattress on the floor in her room and constantly wakes up through out the night waking us up in turn and spending hours to get her back to sleep mine and her dad's relationship is non existent due to this I can not remember the last time we watched something on TV with out having her join us or even sleep in the same bed as him I'm exhausted and my husband is exhausted we both work he is in work for 6 am and drives hgvs and i have 3 kids ages 7 6 and 2 to get up ready to school then work and back to school for pick up aswell as all the other jobs a parent has I just dint know what to do 

Sorry for the long post but any help is greatly appreciated
