Dear Member, as mentioned by you, self motivation works sometimes and other times the disorder is stronger. At such times, instead of fighting and waiting, it is better to seek external support. You have taken your first step by asking. The best route in your case, since it is becoming serious and risk alarm (suicidal feeling) has been raised - kindly contact a psychiatrist asap! Start your medication. Then with some relief, you can start off your psycho-therapy for long term benefits and building your coping skills.
Next Steps
First, share this situation with friends and family. Tell them to keep a watch on you.
