help please

okay so i’ve been struggling to be happy for awhile now. whenever i get sad i think me and my boyfriend should break up because i need time to collect myself and become happier. i feel like he should be with a girl happy and now depressed, i feel like i’m dragging him down instead of lifting him up in life, everytime i mention that to him he disagrees. but i truly think i’m dragging him down with me. he could be doing so much better, instead hes with me. i go through a depression faze at least once a day. i can’t help it and i can’t stop it. should we break up?
