I'm cry much what's wrong with me?

ever since 2 years ago I got really sensitive. now I cry over everything and it's starting to get me mad the last thing I cried about was today when my mom was trying to get me to volunteer for something at my church and I told her now and she might make me so in turn I went to my room under my bed and cried 3 separate times I know I might sound like a spoiled little kid but I can't help myself because if I dont cry I can't speak and if I do I'll cry automatically and nobody know how much I cry I think one of the reasons why I cry is out of hopelessness because earlier in the week I couldn't figure out my math homework and I started hysterically crying and I could barely stop myself and it used to be that I could calm myself down enough that all the redness �on my face and eyes would go down but now for some reason after I cry the red spots don't go down and I'm getting worried because nobody knows and hopefully will never know also I don't even have a room to myself to cry in I ussaly cry in the bathroom which isn't the most plesant place to cry in what do I do and what's wrong with me? please no negative comments because to me this is serious
