I honestly feel for you having to go through this and I'm sure it's not the first time you have. We all deal with depression in our own ways. Each of us is hit by it differently. I wish I had words of wisdom that could just turn it around for you, but even the things I do are temporary.
I find that using distraction helps me get through things that I can't control or face to do anything about. It's not always easy for us to handle and most times it's our own minds turning something into more. I use computer games that make me focus, I use my art to express the feelings and thoughts...my dark art as it's come to be called. I draw, paint and even sculpt in clay to get it out. I do tend to write it sometimes, as a way to vent, but even then I don't always go into details. I'm sure if anyone were to read some of my writings, I'd be put away.
Finding something that you like or can focus on might help, but again, we're all different. What works for me, might not for you. All I can say is, you're not alone. Even that sounds hollow because I've felt alone quite often. Being able to come here and share with others, you might get some ideas on how to deal with these thoughts and feelings in a positive way.
I don't know if you're seeing anyone about this or taking anything, but I know I fought it a long time by myself. Not wanting to look weak....or so I thought that's how it would make me look. I've had good and bad therapists, I've dumped my share of psychiatrists as well and finally found a few that really listened and helped guide me. Yes, I am taking meds for it too. Hate to admit it, but it's helped. Do I still fight it? Of course, but I've found what works for me, most times and use it when I can.
I truly hope you can find what helps you, what gets you through, what distracts you or aids you in your fight. As I said before, you're not alone and I'm sure there are people that have answered you here that would be happy to lend an ear or shoulder in your times of need. If I can, I will.
Please, take care, be safe and do what you need to, to get through this. 🤗 I hope this made sense and might have something helpful within it. My best to you.
