I've hit rock bottom

I overthink way to much about everything and anything then the thoughts repeat over and over to the point where I actually believe it and literally feel like that's what it is . But I know its not true and I know what the truth really is. This is so horrible and is making me go crazy and I feel like I have given up on life but I'm trying still but its not working so I am in a really bad depression and stressed out to the max . I need help . on top of that I'm always worrying about the future and everything and the " what if's and or not yets or until then or this or that or whatever it may be etc " and really gets to me severely . its extremely bad I've gotten worse and I thought I was doing okay but I'm really not. I need help before gets more intense then it already has . I stress about this everyday and all day on a daily basis from when I go to bed and wake up . I feel like I will never get better and I'm very very depressed and stressed ! This terrifies me and because I feel I can't enjoy my life or who I have in my life or do anything because my mind is so set on these things 24/7 that I can't do nothing else or be able to feel any type of way it feels numb after awhile and to the point I can't even cry then I get into a panic attach sometimes. This is not good. Someone help with advice I could really use it ! And would really appreciate It !! ..

He. kindheartedxo. There is hope. I just came out of a very long severely depressed state. It took a hospital stay and a radical change in my meds but I now am feeling much better and have hope for the future. I still have to watch out for my worrying. It tends to bring my mood down. I try to stay in the present and not look to far into the future or at the past. Hang in there. Keep coming here and getting the support offered. I hope you get relief soon.
