Is it normal that i've been feeling anxious and sad for no real reason?
I'm a VERY carefree person. Nothing is a problem to me, and it's chronic to the point that others can become frustrated with me and say, "You don't care about anything, you don't take anything seriously."
But for some reason, the past few days, I've been feeling a lot of emotions that I am not used to. A few days ago, I was extremely melancholy because I felt like I wasn't as close with my friends as I used to be (which isn't true, but I couldn't shake the feeling). Today, I had horrible anxiety because I was worried that someone I love would get in a car crash while commuting to work and die - an anxiety that was triggered by nothing as far as I can tell. Then I had thoughts about how I would lose my will to live if my family members all died and I was the only one left, which made me feel like I don't love my girlfriend as much as I should, which caused me to cry. And so on and so on.
To be honest, I don't like all of these feelings. Now I'm sitting here asking, what the fuck is going on? Why am I being emotional?
Is it normal to feel this way? Bonus points if you can tell me why I might be having these thoughts.
