feeling completely hopeless - need guidance, please

Assalamu Alaikum. i've hit what feels like rock bottom and i've been seriously depressed for the last three months. i'm seeing a professional but it doesn't seem to be helping much, and i'm scared i'm a lost cause. i keep thinking i'll never improve and that life will only get harder. i pray five times a day on time and make dua, but nothing seems to change - things stay the same or get worse. i barely have energy to do anything. i can't study, i skip classes, and i can't start my projects. i pray regularly and often cry in dua, begging Allah for help because it feels like therapy alone isn't enough. i feel out of place around everyone and like no one understands the way i think. i'm angry and ashamed at myself for how irrational my thoughts feel. i really believe Allah is the only one who understands me, which is why i keep turning to Him, but even then it feels insufficient. i beg Him when i'm crying and complain to Him about everything that's weighing on me, yet i don't feel His help. i'm miserable, lonely, and desperate - sometimes it feels like Allah is all i have. is there something i can do to make my duas more accepted? i've been trying to be patient but i'm at my breaking point and i don't know how much longer i can hold on. if it weren't for my faith, i might not be here. i genuinely feel lost and don't know where else to turn; even my therapist seems unsure how to help. i want to try tahajjud tonight hoping it might bring something meaningful. aside from that, is there anything practical or spiritual i can do to start feeling better? any advice, duas, or small steps would mean a lot. jazakAllah khair for listening.
