Should I seek help?

It’s been going on for a couple of years now and it’s usually just intense, periodical mood swings and can sometimes turn into full-on days of pure emptiness. I’ve talked to my counsellor about it and have even talked to my aunt who is a psychiatrist and their suggestions helped (being around different people, distracting myself with other hobbies).

Ever since then the days of mood swings and emptiness have somehow vanished but lately they seem to be coming back. Especially now, it is very much clear that I am experiencing what I used to feel and I don’t know if it’s like what happened to me before or just really intense mood swings caused by my period. Should I get some professional help?
