Molly,

It sounds that you are in a slump of being unhappy and sad.  You want to shift out of that feeling.

I just heard a podcast that interviewed Bernie Roth who wrote The Achievement Habit.  The Science of Success is the particular podcast I listened to.  He talks about needing to solve the right problem.  He talks about reframing the problem. Ask yourself what it would do for you if you solved the problem?

You stated that your problem is not having a boyfriend is the cause of your sadness.  Using this technique, say that if you solved the problem of having a boyfriend then what would it do for you?   You may still be sad.  The problem is not not having a boyfriend.  The problem is sadness.  There are many different approaches in addressing sadness.  Make sense?

I suggest doing regular exercise. Something everyday or every other day.  It does not have to be a big thing.  It could be a 15 minute walk, in Nature if possible.

Writing a daily gratitude journal will help as well.  You have done a good job here to acknowledge the good things in your life. Looking at the good things daily and writing them down will help.

Meditation is also a useful practice in being with yourself and accepting what is. If you are sad and sitting with that sadness and not try to judge it or push it away, it becomes better.
