Please pray for my son

Dear all, Please pray for my son who is so shattered mentally. He has so many things in his mind that is out of his control, he says. I am not sure how to help him. He got into the habit of watching inappropriate things on internet and the consequences along with it. He is so guilty about it, but he says he cannot control sometimes. He cries and gets upset over it. He shares his worries with me sometimes. He is a bright boy but does not study at all. He is now 16. After being lazy and not doing work on time, he starts getting upset and says he wants to quit school. He tells me that he wants to get better, start studying etc, but he cannot do it at all.

He is saying that he is so lonely always at school and outside and that no one considers him as a good friend. He is longing to get good friends.
All this is making me feel tensed, stressed, depressed and everything. I don't feel peaceful at all. He used to be so good at everything, now he feels totally useless and feels that no friends consider him as a good friend and is so upset over it.He is in fact a very loving boy,but as a mother,I am not sure how to help him move forward more confidently.I have also been guiding him in prayer, but now things seem to getting nowhere.I am so disturbed that I am not sure how to explain.Cannot sleep,cannot eat. My husband is such a short-tempered and non-understanding person.Cannot share anything with him. And my husband lost his job too recently. It is so so so so so hard to take all this stress.
I am so troubled.
Please pray for my son. I keep on telling him that God will never leave us and will guide us. But he keeps on telling me now nothing is changing even after prayers. It is so disturbing.
A desperate and heart-broken mother.
