First of all, I would advise that you have a medical check - up just to make sure everything is OK. Thyroid problems can cause energy and anxiety problems. You can chat things over with your doctor as well. Then, if everything is sorted and you feel the inclination, get back into the sewing.
Lots of people have a tendency to dismiss 'women's crafts' - (usually those who don't know or care what is involved) so a humorous way that I have to ignore them is to call them "Philistines" (in my head, not out loud). I don't try to change the attitude and I don't allow them to change mine. Sewing is therapeutic as well as fun. Even if you just get out your material and move it about a bit - it doesn't matter. Do as you like with it.
