Insomnia

Just looking for some reassurance. My 6 month old will sleep at night but wakes between 3-4 hours all night. I’m EBF and doing it all on my own. I’ve never been a great sleeper but it’s got to a point where I have insomnia and can’t sleep. I may get 2 hours a night which is broken and I’m wide awake. It’s really effecting my mental health and causing so much anxiety. I manage to get through the day but the nights come by and anxiety hits again. I feel like my body clock has gone to pot. Can anyone relate? I’m at my wits end with my first baby and really struggling. I do have some support but I can’t nap through the day. My brain is on high alert even with baby out the house. I just can’t sleep no more.
