I Am Back Online After A Long Absence

I had left Similar world's because people had been rude and nasty and had been affecting my mood. In my absence I had been diagnosed with critical depression and had been placed in a mental institution for a month and a half. Then my girlfriend now ex had dumped me after our two year anniversary saying me being depressed had been putting a strain on the relationship that made everything worse. Then my friends now exes had all abandoned me one by one to which I'm now alone because my family doesn't understand I had been in the dark lately and sleeping extremely late I did self harm a bit and I had also have been getting nightmares constantly. My hair had been falling out first in strands then mild clumps from the increasing stress. Nobody wanted to talk to me and any friends I made online and in real life couldn't keep a conversation with me for more then 30 minutes before getting tired of me and leaving so now I just spend my days alone and depressed to which I will also spend Christmas time but nobody cares it's always about them never others but I don't know why I'm posting this nobody will read or care about this anyways 😔😔😔😔😔😔😔😔😔😔😔😔😔😔😔😔😔😔😔😔😔😔
