Welcome to our community! I am sad to hear that you can barely feel any emotions and feel so ashamed and embarrassed about your depression, and don't know what to do from here.
You've mentioned that you know you need medication and need to see a psychologist - I think these are really great ideas, and it is promising to hear that you do think there could be help for you. I think that help exists too. But it sounds like knowing what to do and doing it is actually really hard, and I know from my own experience that feeling ashamed or embarrassed makes seeking help even harder.
So I think it is worthwhile for you to challenge that thought. If a friend suffered from depression, would you think they should be ashamed or embarrassed? Still, I know that we always judge ourselves harsher than others, and I know how hard it is to go and get help. I also suffered from depression and quit therapy a couple of times, because I just didn't want to get help anymore. It feels really embarrassing still to say that I was depressed, as if I'm not a complete human being, but I don't think that of anyone else suffering from depression - it's just a criticism I level at myself.
So I am not sure what more I can add to your own suggestions so far, because I think they are really good ideas. I am saddened to hear that you feel really detached at the moment, and I can understand that the way you are feeling right now may even make it harder to go seek help. But I think getting help is worthwhile and is nothing to be embarrassed about.
I mean, you've already made a start by coming here and talking to us, which I'm really happy about.
