Are waves normal ?

I sometimes feel I get waves with my sensitivity and emotional regulation. Like I can go months without a meltdown but then I will struggle to get though a day without a meltdown. The one good thing is with a lot of work I can generally manage to like it out low key and/or alone

Like I was able to manage twice get have a full time job for a years and not meltdown at work but other times I will meltdown regularly .

That said I’ve never been able to really have social relationships , wear certain things or keep a room or house clean
