Hello dear Brother, thank you for opening up about this 🙏
I'm not sure what resources are available where you're based, but any sort of government/community/ non-profit projects assistance might be worth looking into, perhaps this is something your wife could do? 🙏 Resources and programs of all kinds exist, you may be surprised what you could be eligible for or what is out there to help lighten the load somewhat. One thing at a time. 🙏
I already believe you are a very positive person and capable of so much, as you've stated, though you have been handling a lot 🙏 Resilience like you have shown is really admirable and rare, your family is very blessed to have you taking such good care of them and being a model of overcoming difficulties 💚
I think you should confide in your wife when you feel regulated enough to address this clearly with her, and seek any support (such as local hotlines that could direct you to more resources) about your feelings. You aren't alone in this ever 🙏
