@Viva Benadir can you give me any advice?
Think about the favours of Allah upon you. From your life to health to the breath you take. Your family is a blessing from Allah and appreciate all this blessings.
One way you can make your iman go up very fast. Give daawah. Talk about Allah to someone. Tell them about the greatness of Allah. E.g Allah is khaaliq. Allah is merciful.
Pray in the masjid with jamaa.
Make alot of istighfar and dua. ask Allah to help you with your imaan.
Read the quran slowly and read the meaning too.
Give sadaqah to maskiin or orphan. Do it consistently. Once a month etc
Help your mum and get closer to her.
May Allah help you out and invrease your iman.
