I think I've hit my lowest I've ever been in life today. So I used to have friends, they were from college and of course when we graduated everyone moved away. Now I am horrible at texting and after college my mental health took a severe decline where I've now developed depression. I never told my friends because that's just who I am. I wear the mask and I don't like to burden people. However when I get very depressed I kind of seclude myself and struggle to talk to anyone. Well I guess none of these friends cared about what happened to me as I haven't texted them in a couple months because of how bad my depression has gotten. What pushed me over the edge today is I found out one of them got married and no one thought to invite or even tell me. All of my friend group was there and invited. I was there when that friend got engaged and even before they were dating. I just feel horrible and just don't know what to even do anymore. I just want to disappear honestly but can't. This has truly just pushed me to that point of all time low in my depression.
