You are in luck. There are only two things you need to do and life will be much better.
-1- Question what you believe: Where or from who or how did you ever come to believe that by the age of 21 you should have been involved in a long-term relationship or had a job? Did a parent tell this to you, a friend, or is this some conclusion you derived from an aggregation of Facebook posts? Where did you learn to believe that life is a competition where you are suppose to following the same path as friends or people in your age group?
Your beliefs sound reasonable to you. Someone has planted these expectations as being the "norm" or some type of important metric. They are wrong. You are wrong and I would encourage you to take some time to reexamine your beliefs and why you believe such nonsense. Who is this authority that is shaping your beliefs?
-2- You are inflicted with the dangerous disease of futuritice: It is an unfortunate affliction where a person spends too much time imagining some future that has not happened. They worry about the top of the mountain, spending tons of time thinking about the view or how they will possibly make the climb that they avoid living in the present. It is a dangerous disease, because it is self-fulfilling. The person spends so much time living in their head in some future state, that they fail to get off their a$$ and start making the climb.
Once you begin questioning your beliefs and stop living in your head, life will get much, much better. As you begin to develop new beliefs, beliefs that are actually productive or functional in the real world, you will want to establish your goals, set short term goals and focus on them in the present, not some imagined future.
The reason I asked about the languages is because it can be a very liberating and economically rewarding path depending on what you want to accomplish in life. If you want to use the degree to travel the world you can. But, if you are more interested in staying in one city then maybe begin to look at other opportunities. Regardless, you are only 21 and what you have learned during the last 3 years will be of value in the future.
