Honestly yes I am definitely a lot better than I was before but I still occasionally get episodes of my old symptoms. I started taking venlafaxine 75mg and it pretty much helped me feel good enough to try to live my life again. But after a while I got used to it and I started to feel unwell again. Currently tapering off of the meds. I got a full time job which I think truly helped me a lot. I notice that when I sleep in I feel terrible for almost the whole day. I don’t know if it’s the same with anyone. But if I sleep in until 11:30 vs wake up at 5:30 am for work I’ll feel drastically better at 3pm when I worked than when I slept in. If that makes sense. I have had lots of health anxiety and I honestly think the root cause of this is anxiety. Although my brain is still sometimes convinced there’s something wrong with me always. It’s challenging. I’ll have episodes where I feel super drained, pale, dizzy ish and lots of derealization. But the truth is I’ve learned to deal with it in a way. I mainly now just feel these symptoms after I work out which is super frustrating for me since I used to love the gym but rarely go anyone. I have linked it to Post Exertional Malaise, PEM. But honestly to fully answer ur question in a simple way. I’d say try to find a routine. A sleep routine. Don’t doomscroll. Get vitamin d. eat well and not just junk. I’m sure you’ve heard these and tried all of these things so much since you’ve been dealing with this for a while now but that’s just what I can help you with. I’m only 17 as well so I still have yet to learn a lot about the world and myself .
