So I've been very down and depressed lately and I have been stressing for a couple years straight and now I'm laying in my bed and I'm smelling a smell of burnt rubber that is likely coming from the swamp cooler and so I get up and ask my sister and she says she smells it too. So I was just a little worried but then I started thinking about it and I thought of how for the past maybe year or two every single time I stand up I get dizzy because of blood flow or something related and that got me thinking about how I could be at risk and now I'm checking my phone camera every five minutes to make sure my face isn't dropping. This has just started like maybe 30 minutes before I post this but I swear my stupid brain is making me feel things that aren't real like my arm will feel painful but then I immediately just stop paying attention to it and it goes away. Can anyone relate to this or give me advice? This is not the first time I've been way too worried about a health thing.
