idk bout u but I know me

Idk bout u, but sometimes I get so angry and so sad to the point where I cant feel it anymore. like I'll be so happy for like 3 weeks and one day I'll wake up and I'll lay down under my blankets and start screaming and crying some some times I break stuff, and this lasts about 2 hours before it stops. I have really bad anxiety and I've been thru some shit. And do my bestfriend who I fell in love with got a gf and I got so sad and so mad and I couldn't feel it. but today I woke up and screamed and cried and broke things until my other bestfriend came over brought MCDONALD'S!!! and sat with me as we watched so movies. That's only part of my life
