Meditating When Demotivated

I had meditated for some time for 30 min once or twice daily. Now, I am suffering from what seems to be *anhedonia,* a difficulty in feeling pleasure and being motivated. It makes it incredibly difficult to motivate myself to meditate, and even if I have plenty of time and the yearning to meditate, I cannot seem to sit and do it. **What might one do when motivation is extremely low? Is there no other option than to just 'force oneself' and do it?**
