I couldn't find a forum specifically for sleep disorders, so I'm posting this here, in hopes someone who has gone through this or knows about this can help me.

I recently came across something called "hypersomnia" when I was researching trying to find a cause for my extreme difficulty waking up every day.
Thinking back, I've had problems waking up since I was a teenager. Lately though, it is getting extreme. I usually don't get to bed until 2–3am depending on the day. I'm a manager and work closing shifts at my job, so I'm usually off around 12:30am. It's not a matter of not getting enough sleep, because regardless of if I try to get up at 8 or 11 the next morning, I just can't. My partner tries to wake me up, sometimes I remember, sometimes I respond to him but have no recollection. He put our 8 month old in bed with me so he could go do something, he thought I was awake, because I responded to him, but he came back and I was asleep but our baby was awake. Thank god she did not fall out of bed! He was very frustrated with me, and I felt awful, but I had no memory of him putting her there. He wants me to wake up earlier and it's putting a strain on our relationship. It's just physically impossible for me to wake up. Once I finally do wake up, and get out of bed, my body feels like a bag of bricks. I feel so heavy, it's hard to move. I'm not sure why this happens, it's gotten worse over the years. I had my thyroid checked a few years ago, although it wasn't this bad then, and that was normal. I also have sleep paralysis, although it has not happened in a long time. Any insight would be very much appreciated. This is ruining my life, and my relationship. My partner doesn't understand why it's so hard for me to get up, and he gets so upset with me that I actually contemplated suicide today.

I've had depression for awhile, but as of lately I have not been depressed. The suicidal thought was from stress and frustration about this situation, and feeling guilty that I don't know how to make myself wake up.

I'm also tired all day long, I frequently fall asleep when I try to get my toddler down for her nap, or when I'm holding my 8 month old getting her to sleep, I fall asleep too. Alarms don't wake me, my partner has to try to wake me several times before I successfully wake up. Often I don't remember him waking me, even though I respond. And when I do wake up, I fall right back to sleep and he has to come back later and try again. I also never remember my dreams, I have a dream that I remember maybe once a year and it's always the same type of dream, a nightmare. I don't want to sleep this much, I'm missing out on so much time with my children. By the time I wake up, they have to have naps only a couple hours later, then I get ready for work and by the time I'm home they are in bed. My partner is getting increasingly frustrated with me, and the past couple days I just cry, because I don't know what to do. I feel bad but I physically can't help this. I tried to explain it to him, that I don't want to fall back to sleep when he wakes me, that I want to wake up easily, that I'm not trying to fall back to sleep and that I don't like it at all. But he just says I just have to try harder, I just have to do it, just wake up. He doesn't understand the severity of the difficulty of it.

After reading some I'm quite certain it sounds like hypersomnia? Please help. I don't know what to do anymore. Even coffee can't keep me awake. I could drink a cup of coffee and go right to bed.
