Feeling Overwhelmed and Unsupported

I can't take it all. everyone around me expects me to be able to handle everything and hold it on my shoulders. they expect me to be able to just deal with my health issues and that I can push through them. Well I can't!!! I want to burst out so many times with a lot of emotions in public but I've learned that if you shift things, you can keep more shoved in the bottle you hold things in. I havent been to therapy in a month and I just want to crawl in bed and cry. Do nothing but cry!
