Be brave. You already have been. Write about these things, in a blog. It will help empty them out. Find something you love to do, something that you get lost in. Not drugs or anything like that but a hobby.
Eventually you will be able to see where these shadows are coming from. Then you can face them. Right now I’m in the facing them process. I was in a really bad place as well. I went on meds, I pushed to get off them. They are worse for you.
Try self affirmations, youtube has some great ones.
Keep pushing and keep going. You may not have the answers now, but in time you will…and the enlightenment you will gain is worth it.
Also try to do things for others, help them.
