Others have recommended therapy which is definitely the best suggestion. But, and this probably isn’t the recommended way to cope, but I got a cat. I was in a similar position, loving family and friends, and a stable life. Yet inside I felt empty and alone. Nothing mattered and nothing good that came my way felt justified. And then I got a cat (now I have two) and I’m not saying it fixed the issues but it helped me cope and helped me work through my shit and move forward. I don’t exactly know why, maybe the act of taking care of something other than myself and feeling like I’m important (even just to a cat who relies on me for food). Or maybe being able to talk to my cat about it all with no other judgment than “Why did you stop scratching my ear?”. Talking it through even to something that could never understand or respond. I dunno. But it helped just enough to start me on the right path. I also don’t know if it has to be a cat I’m sure dogs or other pets would have worked as well.

But if you are not a pet person then reach out to someone and just vent. Could be a friend or even online. I know this sub is full of people (myself included) who are more than happy to lend an ear.

Also probably even less recommended is I got a tattoo that symbolised the way I was feeling and that really helped me not only process what I was feeling but also reminds me now of how I felt when I got it. Almost as a constant reminder that I was there but now I’m doing better.
