Why do I feel bored and sad all the time although I take medications ?

You might need a change of medication if you're still feeling that way. You should see your doctor and tell them this. Also, are you able to talk to anyone about how you feel? Maybe you need someone you trust to talk to. You need to think about what is mostly bothering you in your situation, is there anything specific that causes you to be sad? Don't let your feelings take over, have hope that things will get better over time because your situation will change.
