You have the right attitude. Prophet Muhammad (PBUH) was a warrior and there were 101 battle and expeditions in his time, out of which he was present in 28. The Muslims didn't win all of them. There were successes and losses. That tells us that just being a Muslim doesn't guarantee victory, we have to work for it.
The thing we need to remember is that we as Muslims have several advantages that our enemies don't have.
1. The promise of help from God.
2. Belief in heaven. Our dead go to paradise while the enemy goes to hell.
3. Unity. Even if we seem disunited, the disunity in mostly among rulers while most Muslims are very united. We need to work more on this.
4. Prophecies of victory, inshallah.
If we're suffering, then so is the enemy. I see a sudden collapse for them which will leave the whole world stunned. In the mentime we need to remain steady.
