Today i've felt really hot for some reason..am i just sick or can mental health have anything to do with it..?

because i've felt depressed for quite a few years, never done anything about it....lately the intensity has risen and i feel like a dormant volcano ready to erupt using every bit of strength i have to keep myself from having a mental breakdown and lashing out on myself with frustration/confusion....wondering if that might have anything to do with it? I'm never hot, if anything, cold usually...thats why i'm asking..
