Salam,
How are you doing sister Amoeba? Hope you're doing well.
Try to fill up your time with something useful; as you liked to draw why not learn any kind of handicraft: embroidery, patchwork, crocheting, etc.
Learn a new language or increase your computer knowledge by taking a course.
Reading also is an option, you seem very much interested in natural science; fill up your time and read about subjects you like.
Read about islam, the life of the Prophet (PBUH), islamic history, etc.
Find good muslim friends to share your ideas and thoughts with.
Make a time for contemplation (tafakur), it's a form of worship (ibadah)... think about the greatness of God whenever you hear of or read about any scientific discovery...things we perceive as normal are evidence of God's ability e.g. isn't pregnancy and given birth a miracle? ...and say subhanallah.
Keep God in your thoughts at all times ask for His guidance, ask for His Mercy, ask Him to keep any sadness away from you, always ask for His help.
May Allah guide you to the correct path.
