Thank you for sharing your story, I can also relate to this sort of feeling, I have not been excited about much as i've become older with this issue of depression.

I think it takes alot of hard work with a therapist or someone who can put things into rational perspective, and a lot of determination through forcing distractions and well being activities even when it seems impossible.

This has helped me, but still a very long way to go.

Hope this has given support or helped a bit
