Struggling bad

so

I feel so alone like there’s no way anyone is struggling as much as we are, and Im feeling totally hopeless. My baby is preemie, born 5 weeks early and he’s now almost 10 weeks. Things were okay (better than now) before my husband had to go back to work, but now shit has hit the fan. Baby doesn’t like to sleep in long stretches, I’m talking an hour and a half, max. But mainly he’s been sleeping 45 min. And then I’m awake 2 hours trying to get him back to sleep, and the cycle continues. I’m literally falling asleep while feeding him every time. I tried to have a friend come over to help me, but I couldn’t relax and sleep, so I spent the whole rest of the day trying to get any sleep I could and next thing I know it’s 4pm and the sun is down and I’ve only gotten an hour nap in and haven’t eaten anything all day because I’ve been trying to sleep all day. My husband is very kind and tried to help throughout the night because I’m struggling so badly but he has to wake up at 4am for his job so last night he got 3 hours of sleep. It seems at 4am is the time when our son finally wants to sleep more. And we always try to go to bed early around 9-10pm. This horrible cycle just keeps going and I’m not seeing improvement. Everyone says “it will get better” but WHEN? I just want to love on my child so much and enjoy him, but it’s so hard when I’m not sleeping so all I want him to do is sleep, so I feel so neglectful guys 😢 all of my friends who have newborns seem to be sleeping a hell of a lot more than we do and I just don’t get it.
