I Dont Ever Feel Happy Anymore

I really don’t feel happy or that my life is headed in the right direction. And lately, I don’t feel like a person. I’ve detached myself from my wants and needs as a coping mechanism, because at this moment I’m not able to take care of myself. It has been replaced with taking care of someone else who needs it more than I do. And I willingly took on the responsibility because there was no one else, and I wasn’t going to allow the person to fall. It’s how I am. I put others before myself because I’m an empath who feels the emotions and needs of others, and puts myself in their shoes. But I’m not sure how long I can keep it up before I’m drained to the point that I have no energy.
