Seeking comfort and advice 💔 feeling lonely and down, need your kind words

As-salamu alaykum everyone. I've been dealing with a stomach issue for nine months now, and at first it was really severe and overwhelming. I went to many doctors and all the tests came back normal except for some blood in urine, gut inflammation, and it's a long story. Life feels so heavy-I can't go to school, all my friends have drifted away, and it's just depressing. I try my best to pray all five prayers, to be grateful to Allah, and to stay positive, but sometimes I feel like my duas aren't being heard. I know that's not true, and I should push myself to make more dua and keep busy, but I keep losing track of my day. Still, I try to believe that life will change, Allah will open doors, and happiness will come, because this dunya is temporary. Sometimes Shaytan tricks me into negative thoughts when I get exhausted from the same routine, and I regret it. A month ago, I had a dream where someone told me Allah has heard me and good news is coming, but nothing has changed yet. My parents can't take me out much, and I understand their reasons. I try reaching out to people, but they don't seem to care. Even when I visit my mom's friend's house and try talking to their son, they stay on their phones-it's so strange, because if someone visited me, I'd put my phone down. I know humans aren't perfect, and I'd be so supportive if someone came to me, but this is how the world is. This isolation has been going on for three years-no friends, my parents can't do much, and I tell Allah my problems but still feel unheard. I know He removed people to draw me closer to Him, and I try, but life doesn't change. I feel like I'm in a prison instead of a home. I'm both an introvert and extrovert, and I miss being happy, talking to people, going out. When I finally talk to someone after a long time, I get angry over small things. I've tried to change by going for walks, running, going to the masjid, but how do I keep myself busy during this time of patience? Can anyone guide me?
