What to do.

Would a therapist help with this.? So recently Ive been feeling super depressed n have anxiety to the point where i wanna throw up. I’ve had depression before but that’s it n never took the pills it would just come n go throughout the year. But recently me n my bf broke up for a couple of days n I think that’s what triggered everything. He didn’t cheat or anything it was something small n dumb but now being back with him feels weird n different to me if that makes sense. He says he feels the same as before his feelings hasn’t changed n loves me n I do too but I always think he’s doing something for no reason. My brain just puts that in my mind idk what to do I hate feeling this way. I do want to be with him but idk what to do I wanna try a therapist but idk.. i don’t wanna ruin our relationship just bc I be assuming things when he hasn’t given me reasons to even assume.
