Could i have anemia? What do you think?

The only way you are going to get a proper answer is to go to your doctor and tell him how you are feeling. You will then need a blood test to check your FBC (full blood count), and find out if you are anaemic or not. If you don't want to go to your doctor then try increasing the amount of iron in your diet. On the other hand your symptoms could be due to something totally different - so you need a proper opinion from a doctor.
