I am in such a funk that I cannot get snap out of and I need help?

hi, i have feeling very depressed in the last few months and i have no idea why. i have no friends, like none. i thought i had like maybe one but i don’t because i met her at my job and since she quit we haven’t talked. when i try to msged her to say hi she won't respond or she will respond once and nothing else. my job absolutely sucks. i work for a call center and the calls do not stop and i am exhausted. i don’t have any hobbies, i want to find something i like doing but in reality i don’t like doing anything at all. i have a boyfriend but as of recently it feels like we are not together. we don’t talk, if i call him he won’t answer. we barely hangout. we’ll hangout once a week if that but after a while we end up arguing. when i get out of work i’ll try calling him and if he answers me he’s already with some friends. anyway, so yeah im just very bored, sad, depressed. i really dont do anything. i work from home so i spend hours inside my house. once i get out ill go to the gym for two hours come back home and i shower and go to bed. it’s hard making friends now a days and im just so sad. i hate this and I don't know how to snap out of this funk :( i truly dont know if my job, not having any friends or my boyfriend is making me feel depressed.
