This raises a number of related questions. Why did you get a string of disappointments? Are you so untalented and incapable? Unlikely... Or maybe they were just trying to do something else? Did you follow not genuine conscious needs and desires, but imposed by society? That's your unconscious and did not let you go where you, in his opinion, do not need...
Work begins with an awareness of genuine desires, goals and needs. When you can answer the question "What do I really want?" and clear the answer from any kind of husk, then you will have the opportunity to accumulate energy to follow these desires. In this case, the unconscious will already help, not hinder.
And starting to receive positive reinforcement in the form of the results of your own activities, you will gradually get rid of the learned helplessness: conditioned reflexes come and go as self-training.
