get better at finishing things

All through out my childhood and teen years and now adulthood.. I’ve pretty much have been discouraged by my mother and whenever I break down and cry and ask why.. she can never answer for her own actions, and just say I wont amount to anything. but she wishes me good luck in the future.(smh) But this is far from true every dream I’ve had she’s found a way to shut it down.. for example 11th grade when colleges started sending me letters she would always say dont get excited because I dont have money to send you, but turned around and put herself through college for 6 years now.. that hurt me to the core, and to this day she still wont help me go to school. My problem is after years of deferred dreams and negativity drilled into my head by a somewhat of a parent. Unfortunately I’ve begun to believe the negativity and cant seem to follow through with anything I set out to do, and I want to change that.. and regain a CAN-DO attitude.. but I need help and encouragement.
