Hi Zor-el. Welcome to Psych Central. Sorry you are plagued by Dark Thoughts. Driving home I heard this show on NPR radio entitled Invisibilia with a one hour show on Dark Thoughts and how a couple people have struggled with them and got beyond them. I thought it might be of interest to you if you are doing Freudian, CBT, mindfulness or other alternative therapies. Even if you are not in therapy and have thoughts that bother or annoy you, this presentation could offer insights how to go beyond that.
Dark Thoughts : NPR

You can listen to the story (an hour or so) and or read it. I think it is very insightful show. If it is too much to read or listen in one night, come back to it. It is a lot to digest at once.

Glad you have joined our community. Many people here at PC find they can share these feelings and what they are going through with the confidence that people go through similar things and can empathize. So many forums are offered as well as Chatrooms (after you have 5 posts or comments on others posts). Anxiety Chat is 8PM Wednesday 8PM EST. Depression Chat is Thursday 9PM EST

You can also be an active member in other ways like supporting others in their questions, reading articles and posts http://forums.psychcentral.com that are applicable to your area of concern.
