worried about my emotions?

so lately i been crying and very sad... Like i cry for almost anything, im like so sentimental.... Im not pregnant nor its my period because it just ended 4 days ago so... Im not stressing out or anything im only 22 years old.... I dont feel depressed or nothing just feel like crying all the time like a baby lol.. especially when im lonely.. i do have a boyfriend and sometimes i cry with him too its so weird... What can i do to stop crying? I feel like an emotional wreck haha.... I dont want to harm myself or anything!!!! its just some random tears and random sadness.. 😧I mean i love life. i go to college and work from home i still live ar my parents house so it kinda sucks because i wanna be with my boyfriend and live with him already, 😭maybe it's because of that?I always been very sensitive though and emotional when i was young so i guess its normal.. should i take a medication for it? or what can i do to not be crying anymore... like today i cried for at least an hour watching the notebook so ya😱😂
