The uncertainty of security

I am taking up film as my college degree and I got here last 2018 after doing 3 years in a different college. I love the industry, being able to create stories and being in production creating whatever concept we thought of come to life. I've always been scared when the thesis becomes the topic. Now that it is my semester of creating my own short film for my thesis, people are asking me where I want to go or what I want to do, which is a valid question to ask. I do have goals for myself, however, the thought of being in the real world scares the living shit out of me. I know for a fact that I'm not amazing at what I do. With this thought going around my brain, it brings me anxiety. What if no company will hire me, what if my goals are too far to reach, what if I won't be able to do good in this industry? My parents sacrificed a lot for me to be happy with what I do, and I'm so scared to disappoint them, yet again. I was so sure of what my dreams were, and what my goals are, but now that I am one step closer to graduating, the uncertainty of it all is overwhelming.
