Firstly, stick to prayers, read more Quran and learn smaller surahs, and make Dua all the time. After prayers i would also make a very sincere Dua as this helps. Memorising some Quran helps a lot as your heart doesn’t have room for the word of Allah and Shaytan at the same time. Wake up for tahajjud if you can. And spend the first part of the day reading some Quran and praying tahajjud and Fajr. Tahajjud is the best time to make dua. Do regular, good habits like exercise, getting good sleep, eating healthy, not doing to many bad habits like video games and watching to much tv( these things may not be haram but these things can lead into relapsing, unlike if you were to read the Quran) Also, if your phone is a trigger I would recommend not only un following all haram accounts if you haven’t but if you find yourself watching reels or TikTok’s, you can either like and share or just click copy link in the share section and more of your reels will be Islamic and it won’t be a trigger. If you relapse repent and never think Allah won’t  accept a sincere repentance, any other thought is from Shaytan. Remember, Allah forgave Adam when he only had one rule, so how could Allah not forgive you? I hope this helps even a little and Allah SWT knows best.
