2 week old and i’m so tired

I’m 20 and a FTM. My baby was so well behaved at nights for quite a while and only woke for feeds, to be winded & nappy changed. However recently he’s decided he won’t sleep until about 5/6am.

My boyfriend has a cold so he’s sleeping in a separate room and unable to help with our boy as much as we’d like because we’re super scared of germs getting to him!

Last night he just kept crying and crying and wouldn’t let me put him down into his bed despite all his needs being met and I kept comforting him, I know newborns don’t have a schedule but I was stressed as I was at the point of my eyes feeling heavy and I have such a massive fear of falling asleep with him since I roll in my sleep!

I ended up having to step outside the room and let him cry for a few minutes just to regulate myself and not let him see me cry, then I stepped back in and cuddled him again.

He eventually fell back asleep but woke again the next hour, luckily went back to sleep quite quickly after I fed, changed and put more layers on him as our room temp dropped.

I just feel so stuck and guilty whenever I step away from him. I dread when night time comes around because I know he’s going to be upset again easily.

Another worry is my bf has decided he wants to go back to college this year meaning he’ll be going to bed about 10pm, waking up at 6:30ish and leaving at 7:30, then won’t be home til 5:30pm. Then when he comes home from college he’ll be too tired and want a nap so that’ll take to about 6:30pm, and by the time he’s up with him i’ll have about 4 hours sleep if I don’t have dinner, 2/3 hours if I do depending on what food I have, and I also wake every time our son cries even the slightest.

I’m so anxious that I’m going to get overly tired and fall asleep & drop our son once he is back. I feel so stuck.
