Friends drift away and desert you. People you were extremely close to become distant, but God never will. He will walk with you through every struggle and challenge that you face and give you the strength you need, if you ask Him for help.
In 2 Timothy 4:16-18 (https://bit.ly/2HHWB8G), Paul was deserted by everybody. But though he felt alone, God was still with him and gave him the strength he needed to face his trial and speak out for God. In the same way you can trust God to stand with you and give you strength to face your current challenges.
