Hi everyone. I am looking for some advice on how to proceed.

I am almost certain that I'm depressed, have been for a long time and I want to do something about it. However, I think that most of my issues stem from leading an unhappy/unfulfilling lifestyle. 

I live alone and have done for about 15 years, I have been single for 10 years, at my age most of my friends are married and have kids, and I hated my job so much that I quit without anything else lined up. I struggle to find hobbies that are not solitary and there are a very limited number of interest groups available in my area.

I can't help but think that if only I can resolve all of those issues then I'd be happy. But I am sure we all know that finding the energy to tackle these things while in this state and alone is incredibly difficult.

Many years ago I was prescribed citalopram and ended up on a fairly high does. This did little but make me feel like a zombie and I am reluctant to see my doctor again because of this. Perhaps the communication on both sides was lacking though. I am from the UK for context. I'm unaware of any free counseling/therapy services here and after trying private for a while it was ultimately too expensive to continue long enough to get any real benefit.

Any insights or suggestions on what I could do would be really appreciated. I'm determined to fix myself and just need some support to get me started.

Thanks
