Continuous cycle of depression/healing

Its so confusing out here man. I used to think I was just alone, and not lonely, because I’ve always been coping just fine by myself as I’ve learnt effective and healthy ways of dealing with my stuff, until recently. It feels so heavy now. I go through phases of really heavy dread that’ll last for weeks and then begin a new phase where I feel like I’m better than ever. Then the cycle repeats but each time, whatever the feeling is, gets abit more intense than the last time.

Im not really seeking advice here. Probably just anyone who can relate. I just needed to release a little bit.
