I don't feel like myself. Could it be because of "love"?

Honey u absolutely Need to snap out of this this man is old enough to be your father.. It's hard because your blinded by love but as an outsider looking in this is totally wrong and I highly doubt he has any good intentions please don't go back to him just relax and believe in yourself your only 19! You have all the time in the world to find some1 that fits your standards live your life and dw about finding some1 love truly occurs when your least expecting it don't downgrade yourself to some1 like that. Oh and it's ok to be quiet and reserved so long as you ate able to open up to some1 eventually
