Don't worry Allah swt is with you. Read dua Joshen Kabeer once a week for protection and strength. Read every Thursday night Zaiarat Ashooraa with dua Alqama for protection
every night.
If there is a problem on praying on Sajdagah you can pray on a piece of paper, if there is a problem on praying on a paper, then you can pray on prayer carpet in front of them and no need to repeat the salaat. If there is a complication and hardship associated with praying on the Sajdagah then you do not need to put Sjadagah in front of her or in front of any Sunni who becomes annoyed with it and might cause an insult or disrespect to you. As for the marriage with the right person, pray Namaaz Jafer Tayaar daily at night and you will see best results as soon as possible, do not leave this great amazing salaat.
Just keep the faith you are not alone, you have the greatest and the strongest Almighty swt with you. for help call our beloved living 12th Imam AF after doing dua to Allah swt alone, our Imam AS is the helper on the earth appointed by Allah swt.
