Lost and afraid for my faith

Salam alaikum everyone. For the past three months I’ve been going through a really tough time and I’m honestly scared. I feel like my iman is slipping away bit by bit. Nothing in my life seems okay-my deen feels shaky, my health is poor, my job and university are a mess, money is tight, sleep is a struggle… just everything at once. I still try to pray and hold on to sabr but deep inside I get these nasty thoughts that maybe religion isn’t real or it’s not helping me. I hate those thoughts and don’t want them but they keep coming back! I’m terrified that this means I’m leaving Islam or becoming a disbeliever, astaghfirullah. I know Allah tests us and this life is a trial-I truly believe that-but this is just so hard. What I don’t get is why I’d be tested in a way where I’m suffering all the time and can’t even focus on my university or my deen anymore. That’s what scares me most because it feels like I’m sinking deeper. Sometimes I think Allah is punishing me for not taking my studies or my faith seriously enough, even if I’m not sure that’s true-it’s just how my heart feels, empty and heavy. I barely have any motivation to pray now, even though a part of me still wants to. Inside everything feels wrong and I’m hurting every day. Has anyone else gone through something like this? How did you cope? I really, really don’t want to lose my faith. Jazakum Allahu khayran.
