Sisters, I’m struggling with my faith and need your advice

Salaam alaikum, dear sisters. I’m reaching out to those who’ve embraced Islam, especially sisters, because I really need some guidance. Lately, I’ve been feeling so distant from my faith. I still believe in Allah, and I always will, but my heart just feels heavy. Whenever I try to focus on Islam, my mind gets all cloudy. I used to be so devoted, but now I’m barely keeping up with the basics. It’s hard to admit, but I’ve fallen back into smoking, and I feel terrible about it. What should I do? On top of that, keeping my hijab has become such a struggle. It’s not that I mind wearing it outside, but my family keeps making comments, sometimes trying to convince me to take it off. Their words don’t change my mind, but I’ve lost that spark of purpose. I wear it out of habit now, and I can’t find the value in it anymore. I hate feeling this way. Every day I promise myself I’ll get better, but I never follow through. The worst part is, I don’t even feel guilty anymore. Plus, I have almost no Muslim friends. Before anyone suggests visiting the masjid or joining a community, please understand that’s just not possible for me right now.
