I agree with everyone above. It is time to get professional help. I felt just like you do, I was calling in sick to work and asking my professors for an extension on homework deadlines. I finally realized I had to do more when it started affecting my relationships. My psychiatrist is a very nice woman who does not make me feel bad about myself or manipulate me. I am not sure why you think you will be deceived by a professional but that has not been my experience at all. I did decide that the one on one meetings with the therapist were not helpful FOR ME but my psychiatrist kept working with me and I am feeling much better these days.
Also, friends want you to confide in them. That’s what friends do.
You’ve got to do something and since you already feel like life is not worth living, what is the harm in trying something different? Fake it until you make it!!
