Remember that God puts us through suffering and trials in order to make our faith stronger in HIm when we pull through. God warns us against suicide.
Even to your old age and gray hairs I am he, I am he who will sustain you. I have made you and I will carry you; I will sustain you and I will rescue you.
Isaiah 46:4
And so we know and rely on the love God has for us. God is love. Whoever lives in love lives in God, and God in him. - 1 John 4:16
Not only so, but we also rejoice in our sufferings, because we know that suffering produces perseverance; perseverance, character; and character, hope. - Romans 5:3-4
8Finally, all of you, live in harmony with one another; be sympathetic, love as brothers, be compassionate and humble. 9Do not repay evil with evil or insult with insult, but with blessing, because to this you were called so that you may inherit a blessing. 10For,
"Whoever would love life
and see good days
must keep his tongue from evil
and his lips from deceitful speech.
11He must turn from evil and do good;
he must seek peace and pursue it.
12For the eyes of the Lord are on the righteous
and his ears are attentive to their prayer,
but the face of the Lord is against those who do evil."[a]
13Who is going to harm you if you are eager to do good? 14But even if you should suffer for what is right, you are blessed. "Do not fear what they fear
; do not be frightened."[c] 15But in your hearts set apart Christ as Lord. Always be prepared to give an answer to everyone who asks you to give the reason for the hope that you have. But do this with gentleness and respect, 16keeping a clear conscience, so that those who speak maliciously against your good behavior in Christ may be ashamed of their slander. 17It is better, if it is God's will, to suffer for doing good than for doing evil. 18For Christ died for sins once for all, the righteous for the unrighteous, to bring you to God. He was put to death in the body but made alive by the Spirit, 19through whom[d] also he went and preached to the spirits in prison 20who disobeyed long ago when God waited patiently in the days of Noah while the ark was being built. In it only a few people, eight in all, were saved through water, 21and this water symbolizes baptism that now saves you alsoâ€â€not the removal of dirt from the body but the pledge[e] of a good conscience toward God. It saves you by the resurrection of Jesus Christ, 22who has gone into heaven and is at God's right handâ€â€with angels, authorities and powers in submission to him. - 1 Peter 3:8-22
Hope those verses helped.
