My weight fluctuates— I’m at my heaviest— should I throw out everything I can’t fit in?

I have piles upon piles of Levi’s that I can’t wear because they are size 25 to 30 and I am now up to a size 34. I have congestive heart failure and I retain fluid so I don’t know when my weight is going to go down I am trying to exercise, but I have zero energy in the overwhelming Drain of just stuff in my house is killing me. Should I throw out all the things that I just don’t fit in anymore and lose the idea that I will ever fit in these clothes and buy things as I go that fit me nicely.

I also just lost a pregnancy at six months in so I am at my highest weight
