A post about anxiety/life

There really isn’t much point to this post other than me just speaking what’s on my mind.
Since 2020 I’ve developed health anxiety and I guess what would a fear of death. I am a what I would consider pretty healthy person. No chronic health issues or anything to be worried about. Yet, thought about having a heart attack, stroke, cancer, etc seeps into my mind almost constantly anytime some weirdness happens within my body. I’m mostly been able to manage these thoughts and keep myself from spiraling. Mindfulness, journaling and therapy have done wonders for my racing mind. Progress!
Also with the health anxiety, I started to get the feeling I was going to die soon. Oddly it wouldn’t come at the same time as the anxiety (though I’m sure they are connected) but it would come in as depression. At these times I would just feel hopeless and sad and bit of fear that maybe my time was coming. It hits me hard on days like today, were I’m having a great day and everything is good but in the back of my mind I have this fear “If you’re feeling this good, it must mean you’re going to die soon.” Or “ you can be happy or you’re going to die”. This is a little harder to manage than the anxiety. I use to have a good day and then would intentionally mess it up to not feel like I was going to die. Now, I just accept it for what it is. I don’t want to live my life miserable because I’m afraid to be happy.
All this is a progress and I struggle some days but I’m moving froward. I feel like I’ve learned a lot about myself and honestly have grown as a person because of it (A positive to anxiety and depression if any? haha). If anyone has any similar feelings, I’m curious to know how you deal and what helps. Also if anyone just needs an ear I’m here to listen. I know it helps me feel better to have someone listen sometimes.
