First of all. STOP! Realize that there are other solutions to your problems.

Secondly, you need some professional help to deal with your confusion. Talk to a therapist or a counsellor to sort out your problems. You need to figure out what the problems are first before fixing them. Sleeping with other men is just at temporary solution. When you wake up the next morning, your problems will still be there.

Thirdly, confied in friends and family if possible to help you out.
