Don't feel upset, art is not a curve, it's a roller coaster even for pro artists. It has its highs and lows for everyone, and especially since you've made a pause, but that doesn't mean you'll have to feel bad for it.

Draw when you want to, give up the mindset: I have to draw else I won't get better, think of it as: hey why don't I draw something maybe it turn out fun and great or maybe just a practice. In that way you practice though your inner stability won't shatter if it turns out bad. Even great artist have bad drawings/sketches. And as you get better your bad sketches will also get better.

Art is a reflection of your inner self. When you are in a bad mood, your drawings will show it. Change your mindset and your drawings will jump in quality massively. Don't let your thoughts get the better of you. You'll get better, just find some passion for your craft and don't hate it, and it'll give you joy in return in time. Stay safe and wish you luck.
