My daughters sleeping is getting worse any advice?

my daughter was 1 on friday and she has been cosleeping with me and her dad since 6 months old because she refuses to sleep in her cot whatver we do so we gave up. now she refuses to sleep anywhere unless either me or her dad are close up to her such as holding/cuddling her and i feel so restricted and we never have time as a couple anymore due to this. if she falls asleep anywhere other than our bed she wakes up 10-20 minutes later but will sleep hours if were holding her or in the bed with her, i think shes got so used to the closeness shes slowly refusing sleep elsewhere now and its becoming more impossible by the day to get her to sleep in her cot. we considered getting her a toddler bed and putting it next to our bed until she learns to sleep alone then move her to her own bedroom, would this work? does anyone have experience with this? im starting to feel more and more depressed and i dont have any energy for anything so im struggling to do every day things because im not getting sleep, and getting her in a routine is proving as difficult as she adement things will go her way or no way and i just dont know what to do shes my first baby and ive tried everything and now im giving up. if anyone can advise me id be so greatful, any time i try and ask advice from health visitors etc they just make their opinion on co-sleeping known and not give me any advice on hwo to stop doing it. thanks in advance.
