Ramadan Struggles with Depression

Salam everyone, I've been dealing with really tough depression-sometimes sleeping 16 hours a day, struggling to do basic stuff like keeping up with hygiene, finishing tasks, and just handling everyday things. Even the simplest tasks feel impossible for me. Alhamdulillah, I turned to Islam for peace and truth and reverted. But here's my issue: everything feels like such a huge effort. During Ramadan, I woke up super dehydrated today but missed suhoor and drank water right after Fajr time ended. Does that mean I need to fast extra days as kaffarah? Praying is a real struggle too; sometimes I sit for an hour or two just trying to get myself up for one salah, and it's a whole mental battle. With Ramadan here, I feel like I'm sinning more because I'm not praying enough, and now with this fasting mistake, it's overwhelming. Plus, there are all these missed prayers piling up that I have to make up someday, and honestly, I have no idea how I'll ever manage that. The backlog just keeps growing, and it's causing so much anxiety, even though I came to Islam looking for relief. And since I'm not considered 'insane' in Islamic terms, I'm still accountable, which just adds to the stress. All this is really derailing me, and the more prayers I miss, the more they pile up. It feels incredibly hard right now.
