I ask Allah to help you and give you strength. Some recommendations:

1- Remember that Allah created us for such situations. This is an opportunity for us to show our faith. One of Prophet Yusuf’s greatest struggles was with this own family. His brothers tried to kill him then threw him in a well then sold him as a slave. But in the end Allah compensated him. All Imams had to deal with difficult family members. So remember that one reason why we are here on earth is to deal with such trials and pass them. Everyday that you pass such a trial Allah elevates you infinitely.

2- Imagine you are in a play. If you were told there is a play and it involves a scene in which you have to deal with your mother (in the play). It wouldn’t bother you because it’s a play. Well the reality is that this world is one long play. Allah is the producer and He is evaluating. Everyday remind yourself before seeing your mother that this is part of my play and my scene. This gives you a lot of strength.

3- Do sujud for several minutes each night and with a deep breath each time say: سبحان ربي الاعلى وبحمده (subhana rabbial a3la wa be7amdeh)

4- Before sleeping, say 100 times لا اله الا الله (la ilaha illa allah) and take a deep breath each time

5- Put the Qur’an on your heart and recite verse 82 of Sura al-Israa:
‎وَنُنَزِّلُ مِنَ الْقُرْآنِ مَا هُوَ شِفَاءٌ وَرَحْمَةٌ لِّلْمُؤْمِنِينَ

6- Read this Dua daily:

7- Everyday pray 2 rak’as like the morning prayer, then when done gift it to Imam Mahdi. Say O Allah I offer this prayer as a gift to Imam Mahdi. Then talk to Imam Zaman and ask him to help you with this situation. This prayer is very effective

8- After the morning prayer, put your hand on your heart and say 70 times يا فتاح (ya fatta7)

May Allah facilitate it for you.
