How valuable is an MSP on a resume?

Hey everyone, so after years and years of trying i finally managed to get into the IT field working at a small MSP (only three techs). I’ve been here going on six months and i actually enjoy the workload. it’s stressful and i am never sure if exactly what i’m doing because i am constantly being introduced to new environments/systems, but i truly feel that i’m learning a ton. there is an issue however. the boss is pretty abusive towards me specifically. he constantly insults me and berates me, anytime he opens his mouth to say something to me it is almost always negative. it has made the job completely unenjoyable and i am ready to go. will this six months of experience be valuable on my resume or should i put my head down and endure it for longer? i’d really rather not spend another three years trying to get back into the field.

i also as of right now do not have any certs, i was ready to take my a+ 1101 before i hired but the workload has made it difficult to study.
