Finding peace through trials and hardship

Assalamu alaikum, dear brothers and sisters. I'm reaching out today hoping for a bit of support and comfort. I live in a predominantly Muslim country. Islam here has taken on a more modern feel, so things are generally acceptable for people, aside from eating pork. But it can be a tough society to live in, and parents can sometimes be overly critical and harsh towards their children. Since I was young, I've experienced seizures that I could never really explain to my family. Because of the way many people think around here, my mother would sometimes make fun of me, thinking I was just seeking attention. During these episodes, I sometimes see or hear things that aren't there, like visions or voices. It's not epilepsy-doctors haven't been able to give it a clear diagnosis. I just go into a sort of trance and stay still, or if the vision is too upsetting, I might faint. It wasn't until my teenage years that I started therapy, because I felt so low that I considered ending my life-but listening to the Quran helped pull me through. I was later diagnosed with Borderline Personality Disorder, because when I get angry, I can lose control, and afterward, I often don't remember what happened during those intense moments. I believe this is a test from Allah, and I remain faithful. I once had a dream about the Prophet (peace be upon him) where it felt like I was present when he passed away. The setting was a desert with tents and torchlights, and I was called into one of the tents. Inside, there was a coffin covered with a green blanket, and even though I couldn't see him, I just knew with absolute certainty that it was him. I sat there crying my eyes out until I woke up. Another dream I had before that was about performing Hajj. I saw the Kaaba, and everything was done just as it should be according to the rules of Hajj. For about the past three years, I've struggled with falling into sin. I've been in relationships that involved actions considered sinful, even if not the most severe form. I often deal with hallucinations, hearing voices, having seizures, and migraines that don't respond well to medication. My anger sometimes leads to episodes where I lose myself and say things I regret. I wore the hijab for three years but stopped when my mental health took a serious turn for the worse this year. My seizure medication isn't working like it used to, and I'm having to take higher doses. Each day feels like an immense struggle. My doctor has advised me not to fast due to my health conditions. I would really appreciate any advice or words of comfort. Some days, I feel like I'm drowning. I've been trying to pray as much as I can-I often pray Isha and do my best to perform the other salah whenever possible. I just hoped to hear from my brothers and sisters who might understand. Jazakum Allahu khairan, and may Allah bless you and your families.
