HELP !!!!

Okay so I really really need help and advice

Okay so I have been experiencing some symptoms over the past few days and these include headaches, dizziness, nausea, weakness and my vision is blurry but that is because I need glasses for long distance.I am a very stressed out anxious person and tend to worry quite a lot I have also been on my phone a lot more due to lockdown in my country but I am really beginning to worry so if someone could help me out I would really love it.

Thanks 💕
