You have named a number of areas in your life that make you unhappy. One potential problem area is your relationship with your boyfriend. He has a problem with addiction related to excessive time on the computer. You also stated that he does not have a job. The reason he does not have a job may be related to his addiction.
Other issues that you mentioned include the fact the you feel as though you have an addiction to chronic masturbation. Another potential problem is that you are having sex with men for money. You also described being emotionally unstable, grieving the loss of your father, you may be experiencing stress associated with your mother being in a wheelchair, and you “enjoy” hurting others and animals. Those are all signs of instability.
It is possible that the recent loss of your father is the cause of or has exacerbated your problems. You could greatly benefit from outside intervention. My recommendation is to see a therapist.
Don’t ignore your problems. Much of what you have described is abnormal and it is hurting you and potentially others. I’m not certain how the mental health system works in your country but it would be advisable see a mental health specialist as soon as possible. It is especially important to do so soon, since you feel as though you cannot control your behavior. Please take care.
