I have strong feelings about SSRI medication, and while I've heard a lot of wonderful stories from people who have benefited greatly from it, it still seems like a symptomatic treatment at best.
If you can avoid medication at all costs. They are not a cure for depression all they do is numb you to your own feelings so you can still go about your life as normal. But your not normal you are emotionally numb inside.
My ex had problems with depression and anxiety the last 2 years of our relationship. We just ended a 6yr relationship 2 months ago. She was put on 3 different types of medication and they all seriously fucked up her up. There was a point where she cried for hours every night for 2 weeks before I could drag her back to the doctor. She later told me durning that time if I was not there she would have killed her self. This was not from her depression it was from the medication. The next two pills made her an emotional shell with no feeling at all. She had no feelings for me or about anything else going on. When we split she couldn't even cry because the medication wouldn't let her. Which of course makes things even worse for her. Feeling the need to cry, wanting to cry, and then not being able to have that emotional release was torture. (Note: She split up with me, I tried everything in my power to help.)
I personally had some depression after high school since the people in my town all moved away to college and I was stuck for financial reasons. Best thing I did at the time was get a job as a waiter. It gave me the social interaction I needed and got me out of the house.
You need to change! If you work from home and never leave then take a break completely most affiliate shit is automated anyway. Consider a job somewhere simple just for your mental health.
If you are at your house all day, stop working there all together. Say you can only work outside the house, get a laptop and go coffee shop hopping.
If you need friends go to meetup.com and try a few meetups, also see if reddit.com has a subreddit for your city. Ask a local bike shop if there are any social rides in town. Many host weekly social night rides, if so buy a bike and go.
If you hate your city get the hell out, you will never be better staying in a situation that you do not like. Look for places that have what you are looking for and start picturing your self living there. Check rents on craigslist, look at the meetup/reddit, look at places to eat with yelp. Start making a virtual life there, say you will live at a house, you will eat at this place near by, tuesday night you will go on the night ride etc. If you start to feel better virtually moving then you will feel better in the new area.
Pills will not help. They will only fuck you up. They are made so sheep who feel sad about their shitty lives can continue living them without feeling. The only time you should ever consider them is if things are so bad solo at you feel you may hurt yourself or others, the pills will stop that.

R: Never take pills for depression unless you are a harm to your self or others. Cure depression by changing your lifestyle.
