I'm thinking about offing myself, is it a good idea?

No, it is not a good idea. Think of your family. What would that do to them. They would never get over that. Talk to a minister, or a therapist. Maybe you don't have friends because you don't reach out to them. Get involved with a group and volunteer, see how good that makes you feel. You then will meet good people and have good friends that you meet there. Volunteer at the local food pantry, or something like that. See how good it makes you feel. My Mom used to say, "no matter how bad you feel, look around and you will see someone worse off than you are". And it is true, God rest her soul. We had nothing when I was growing up, but she always had a hand to help a neighbor. Helping other will help pull you out of the funk you are in.
