… Depression is just like any other condition - it can be chronic, depending on the sort, and sometimes people who are prone to it must take special care to be certain that their head, emotions and feelings are always (for the most part) in the right place, and take steps to correct it when it is not.
It sounds like you’re doing all of those things. It’s great that you are seeing a therapist, and also good that you are taking medication. However, if it’s been 4 weeks on the meds, and you haven’t seen much improvement yet, you may consider telling your doctor, and possibly altering your prescription.
I have found that the best thing to do during a low period is spend time with the people who understand and are patient with you. People who don’t have problems with depression don’t always understand, and you mention that your friends don’t “get it.” That’s not uncommon. And it’s not their fault. They’re very lucky if depression has never touched their lives.
That said, you need to find some peers who can understand you (aside from any at this board). Find an anonymous support group in your hometown if you don’t have a friend or two who’s “been there, done that.”
Also, I would suggest looking deep into your mood right now and finding something … anything … that gives you a bit of pleasure. If it’s not the horses, that’s okay. Maybe it’s a book, movies, or even the silliest TV show. You need something to look forward to every day, even if you have to force yourself. It’s likely that you still feel numb and a bit purposeless. That’s completely normal. Once your meds get into your system, you’ll see a difference, bit by bit.
I’m not sure your age or stage of life, so I can’t tell if you work or go to school. But maintaining normalcy in those realms can be a challenge, as well.
Obviously, this is something I know a lot about. I’ve been through it for my own set of circumstances. One of the things I work for in my adult life, during my free time, is greater Depression Awareness. I know, it’s oh-so-very Tipper Gore, but when I went through it myself, there was a lot of shame and second-guessing … and it kept me from getting the help I needed right away. I wasted so much time worrying about the fact that I was “defective” or “weak” instead of getting right to the point and addressing the causes and effects. That’s why I’m so open about it today. I’m a grown up, I’m actually a really strong woman professionally and personally, but I will always … ALWAYS … have to stop and check my head and make sure I’m on the right track. Like some people check their blood pressure.
Life is hard sometimes … for everyone. I just want to say keep at it, day by day, and continue to watch your progress and consult your doctor and pretty soon I’m willing to bet that you’ll see a difference. And, hopefully pretty soon, you’ll feel stronger, and going to the barn will become a pleasant high-point in your life again.
Best of luck to you!
