I'm going through similar anxious feelings as well, and I've always turned to Philippians 4:6-7
6 Be anxious for nothing, but in everything by prayer and supplication, with thanksgiving, let your requests be made known to God; 7 and the peace of God, which surpasses all understanding, will guard your hearts and minds through Christ Jesus.
Psalms 91 is also a good one:
1 He who dwells in the secret place of the Most High
Shall abide under the shadow of the Almighty.
2 I will say of the Lord,
“He is my refuge and my fortress;
My God, in Him I will trust.”
3 Surely He shall deliver you from the snare of the fowler
And from the perilous pestilence.
4 He shall cover you with His feathers,
And under His wings you shall take refuge;
His truth
shall be your shield and buckler.
5 You shall not be afraid of the terror by night,
Nor of the arrow
that flies by day,
6
Nor of the pestilence
that walks in darkness,
Nor of the destruction
that lays waste at noonday.
7 A thousand may fall at your side,
And ten thousand at your right hand;
But it shall not come near you.
8 Only with your eyes shall you look,
And see the reward of the wicked.
9 Because you have made the Lord,
who is my refuge,
Even the Most High, your dwelling place,
10 No evil shall befall you,
Nor shall any plague come near your dwelling;
11 For He shall give His angels charge over you,
To keep you in all your ways.
12 In
their hands they shall bear you up,
Lest you dash your foot against a stone.
13 You shall tread upon the lion and the cobra,
The young lion and the serpent you shall trample underfoot.
14 “Because he has set his love upon Me, therefore I will deliver him;
I will set him on high, because he has known My name.
15 He shall call upon Me, and I will answer him;
I
will be with him in trouble;
I will deliver him and honor him.
16 With long life I will satisfy him,
And show him My salvation.”
I'll be praying much for you, be encouraged
