Sooo using a throwaway account because a lot of this is personal obviously. I have never really considered myself as depressed until recently, although I am starting to think maybe I was depressed for much longer and recent events made it worse (and therefore more noticeable).

I developed a crush on a girl (who is a coworker) about six months ago (we are dating now). Simply hanging out with her made me very happy, but days that I didn't work with her made me very depressed (lack of appetite, sleeping all day, didn't want to do anything). I kind of figured this would fizzle out over time, but six months later and it is still a problem.

The only reason I mention this is because I feel like right now, she is the only thing holding me together, and that if anything were to happen, I would come crashing down. It's as if she has become a crutch for these emotions, and it's unhealthy and something I would like to avoid. 

I have tried exercise, meditation, and forcing myself to go out of the house with friends (which has helped a little)

I am currently in therapy (only three weeks so far, but I figured I would try it out to see if it helps).

I have been tested twice for depression, both by my therapist, and my doctor. When I was given the test by my doctor, I was actually on a good streak, which is why I don't think any treatment was mentioned then, but lately it has seemed to come from nowhere. I will have days where I feel fine, and then other days where I am feeling terrible with no explanation as to why. 

So far, I am considering making an appointment with a psychologist, but I am not certain whether this is even the right course of action. I have nothing against medication, but the thought that it can change my personality kind of scares me. If anyone could share their experiences, it would be much appreciated.
