Advice needed - should I continue with titration

I am panicking and spiralling I started elvanse 30mg this Tuesday and had an amazing day like wow I can't believe I am cured type of day. Done so many things, however had a very bad stiff and moving jaw. Then the same night I couldn't fall asleep till 5am, like I felt tired but my body was awake although I took medicine around 9am. Then the next day I tried taking the medicine an hour earlier and started losing effects at around 4pm and completely struggled to stay awake at 7pm, but when I went to sleep I struggled to fall asleep and stay asleep. During the day I just felt extremely anxious and jittery. Today I feel insanely emotional and sad, I feel like it doesn't really help me to complete any tasks but just makes me feel shit, shit about having ADHD and shit about the medicine not working, and confused that it worked the very first day. I also constantly feel super hungry. I work full time and also have study for upcoming exams which I struggle now and I also used to go to gym regularly and since medicine I feel afraid to go and exercise or even to meet other people, just feel like I am such an emotional wreck and just want to isolate myself, also I have intense headache for the last 72hr that just doesn't go away. I don't know how to feel about any of this, I panic I might not have ADHD and it is something else I have, and I don't know whether it is even worth it for me to stay on this titration. I worried about the impact it will have on my mental, physical health and exam results especially that I am due to increase the dose to 50mg. I am a female so I don't know if it is impacted by my hormones , has anyone had a similar experience? If so, did you continue or stop with titration and if you continued did it get better? Any advice?
