All I want in life is to feel good.
Why do you strive so hard to feel good?
I think I deserve it after all the hard work I've done
It is good to reward yourself when you have worked hard. Thus you are allowed to seek pleasure for your reward.
I know, but I just feel I have no time to seek out those pleasures.
I can understand that. Maybe what you should do is take a vacation away from work to focus on yourself. This would be very beneficial to you and shed a lot of stress off of you.
