It certainly will take time to resolve. It may not return to normal, but it is not possible to predict what is going to happen this early after surgery. Be patient.
After breast reduction, you should be in your house doing nothing for a week. After that you can go back to work. No exercise for 1 month. By 6 weeks most people are able to do cardio and will feel very well. You should be able to go on holiday.
It is not really possible to change the breast for FTM without surgery. You need to find a surgeon that specializes in the procedure and speak to them. At your young age they will require that you speak to a counselor to help you make decisions.
