Motivation and daily practice are the key. I know people who have found practice by listening to radio / TV in the foreign language they want to learn - if a programme motivates you then you find the vocabulary in a dictionary. Ditto reading the newspaper websites - I used to enjoy MidiLibre when learning French, and I'm sure many exist for Spain. There is nothing wrong with you other than introducing the word 'wrong' into your mind map. The only person who gets nothing 'wrong' is the person who tries nothing. Allow yourself to chatter and make mistakes in Spanish and encourage more fluent speakers to correct you if you do. If they find it funny, smile along with them.
With practice and encouragement you will find it ever easier to retrieve the words and phrases that are the daily building blocks.
