Can I come back to Islam?

Assalamu alaikum, brothers and sisters. I’m feeling really lost and ashamed. I did some foolish, satanic things without even realizing, and I stopped reading the Quran for three months. I haven’t prayed namaz properly for six years-just went to a few Jumma prayers. On top of that, I struggled with a bad habit regularly. I’m scared the shaytaan is messing up my life and my relationship with my family. Am I even worthy of Allah’s mercy? And if yes, what’s the proper way to come back? Please, I need guidance. And yeah, don’t believe everything you read online 😭 they mix truth with a thousand lies.
