Yes, it will be worth the effort. Everything you do to help yourself is going to be worth well. No matter how much you think how worthless yopu are to your family, it's not the same for your family. Kids who don't have both parents usually have a bad life. Drugs, fights, drunk, smoking, etc.... Kids who have both parents are usually healthy. For me, if I have a kid, there will be no me. My life is irrelevant, it is about my kids, not me. No matter how hard life is, I will survive for my kids. At least till he have his own family.... Finding a GP is like finding your true love. Not every Doctor can help you. You just need to find the right person....if ur current GP can't help you, find another. If the next can't, find the other. When you find a good doctor, it will worth it, I promise. Please do so not for yourself. I understand the pain, it's scary yet tempting, but don't do it. Fight harder, not for yourself, but for your son. I don't know what causing you all of this pain, and I understand it really well. Most of us do.... I'm still struggling too, but I will live. You must too.
Anyway, you cannot write methods here, because it is harmful for some people here, this is suicideforum.com for a reason, and many people here are vulnerable.... I hope you well
Again, don't give up.
